Rose Costa is a Brazilian model best known publicly for her former relationship with American actor James Marsden.
Rose and James share one son, William Luca Costa-Marsden, who was born in Los Angeles on December 14, 2012.
Although her family connection generates the greatest search interest, Rose had an established modeling identity before William’s birth. Contemporary reporting connected her with Ford Models and described her as a Brazilian model.
However, much of the longer biography published about Rose online remains difficult to verify.
Celebrity websites commonly provide an exact birthday, height, education, former partners, net worth, luxury-brand clients, and detailed childhood history. Most of these claims do not come from Rose, an official agency biography, a public record, or a dependable interview.
The name also creates an unusual search problem.
Several people called Rose or Rosa Costa appear in the supplied competitor results. They include a Spanish Olympic swimmer, women whose obituary pages were published in 2024, an artist with a personal website, and a Brazilian entertainment professional listed on IMDb.
Those people should not automatically be combined with James Marsden’s former girlfriend.
The strongest public evidence supports a narrower biography.
Rose is Brazilian, worked as a model, had a documented connection with Ford Models, briefly dated James Marsden, and became the mother of his youngest son.
She also appears to maintain a public Instagram presence under the name Roseane Costa, where she has shared selected family, travel, and lifestyle moments.
Nevertheless, Rose does not operate like a conventional entertainment celebrity. She gives few interviews and keeps important personal information outside mainstream reporting.
Quick answer: Rose Costa is a Brazilian model and James Marsden’s former girlfriend. She gave birth to their son, William Luca Costa-Marsden, in Los Angeles on December 14, 2012. Rose was associated with Ford Models and appears to use the public Instagram name Roseane Costa, but her precise age, current agency, relationship status, residence, and net worth remain unverified.

Who Is Rose Costa?
Rose Costa is a Brazilian model who received wider entertainment-media attention through James Marsden.
Marsden is known for film and television work that includes X-Men, The Notebook, Enchanted, 27 Dresses, Westworld, Dead to Me, Jury Duty, and the Sonic the Hedgehog film series.
Public interest in the actor naturally extends to his relationships and children.
However, Rose’s identity should not be reduced entirely to one relationship.
She had a modeling background and was publicly associated with Ford Models.
That professional detail appeared in reporting around the time she and James welcomed their son.
Rose has since maintained a quieter public profile than many people linked with major actors.
She has not built a reality-television career, released a celebrity memoir, or participated in a continuous series of relationship interviews.
Consequently, the verified record about her remains relatively small.
Why Is Rose Costa Famous?
Rose became broadly searchable after reports connected her with James Marsden.
Their relationship attracted attention because Marsden had recently separated from his wife, actress Lisa Linde.
When Rose became pregnant, entertainment publications began identifying her as a Brazilian model and reporting on the expected child.
William’s birth in December 2012 increased that attention.
Search interest later continued for several reasons:
- Marsden became increasingly famous
- William appeared with his father at public events
- Rose shared occasional photographs of her son
- James discussed fatherhood in interviews
- Biography sites published competing stories about Rose
- Several unrelated people with the same name appeared in search results
Rose remains known primarily through this family connection.
However, established reporting consistently recognizes her as a model rather than merely describing her as an unnamed former girlfriend.
Is Rose Costa a Brazilian Model?
Yes.
People, ABC News, Page Six, and other established entertainment publications have described Rose as a Brazilian model.
This is the strongest independently supported profession connected with her name.
That does not necessarily mean she remains a full-time model today.
Modeling careers can change substantially over time.
A person may move between:
- Full-time representation
- Freelance work
- Commercial assignments
- Editorial projects
- Lifestyle content
- Private business
- Family responsibilities
- Another profession
Therefore, the accurate description is that Rose has worked as a Brazilian model.
Her exact 2026 employment arrangement remains private.
Did Rose Costa Work for Ford Models?
Contemporary reports connected Rose with Ford Models.
Page Six described her as one of the Brazilian models associated with the agency. Modeling-production posts also identified her as a Ford model during photo shoots.
A LinkedIn profile using her name lists Ford Models as professional experience, although LinkedIn alone would not be sufficient authentication.
Together, the contemporaneous press and industry references support the conclusion that Rose had a professional association with Ford Models.
However, the exact details remain unclear.
Public records do not establish:
- Which Ford office represented her
- Her contract dates
- Whether the agreement was exclusive
- Every market in which she worked
- Her booking rate
- Her complete client list
- Whether the contract remains active
Therefore, the article should say that Rose was associated with or represented by Ford Models, not that she is definitely signed with Ford in 2026.
When Did Rose Costa Start Modeling?
Some biography pages state that Rose joined Ford Models in October 2006.
However, no accessible official Ford archive or interview from Rose confirms that exact month and year.
The date appears most often on celebrity-information websites that do not show the underlying agency document.
Consequently, the precise start date should remain unconfirmed.
It is reasonable to say that Rose was already working as a model before William’s birth because 2012 reporting identified her professionally.
That is stronger than assigning an exact career launch date without documentation.
What Kind of Modeling Did Rose Costa Do?
Publicly indexed photographs suggest fashion, beauty, editorial, and lifestyle work.
Nevertheless, a complete official portfolio is not currently available through a recognized model-agency page.
Generic biographies sometimes claim that Rose worked for major luxury companies.
Names repeated online include:
- Louis Vuitton
- Hermès
- Christian Louboutin
- Chanel
- Lancôme
These claims require caution.
A model may appear in an editorial photograph wearing a designer product without being hired for an official brand campaign.
Likewise, sharing or discussing a product on social media does not establish a commercial contract.
A dependable brand credit should come from:
- The brand
- A recognized agency
- A campaign archive
- A magazine masthead
- A photographer’s official credit
- An established modeling database
Without that evidence, the article should not present the luxury-brand list as verified.
Is Rose Costa Still Modeling?
Her current modeling status is unclear.
No active Ford Models portfolio was located during this research.
However, the absence of a public agency page does not prove that she stopped modeling.
Models may:
- Change agencies
- Use a married or expanded name
- Work through direct bookings
- Focus on commercial clients
- Represent themselves
- Work internationally
- Reduce assignments
- Leave modeling without announcing retirement
Rose has not issued a widely reported retirement announcement.
Therefore, the safest answer is:
Rose Costa has a documented modeling background, but her current agency and level of professional modeling activity have not been publicly confirmed.
Did Rose Costa Become an Actress?
No dependable evidence establishes a public acting career for the Brazilian model.
The confusion comes primarily from IMDb.
The IMDb page associated with her name lists work connected with Brazilian productions.
However, the visible title describes her through casting or production-related credits rather than clearly establishing acting roles.
Furthermore, IMDb does not explain how it verified that the credited professional is the same Rose Costa who had a child with James Marsden.
The overlap may be accurate.
Alternatively, the database may have combined two people with the same name.
Until an established production source or direct biography resolves the issue, Rose should not be called an actress.
Does the Rose Costa IMDb Page Belong to Her?
The answer remains uncertain.
The page names William Luca Costa-Marsden as her child, which suggests that IMDb intends the profile to represent the model.
At the same time, the professional credits relate to Brazilian film and television production.
No dependable article about James Marsden’s former girlfriend mentions those projects.
There are several possibilities:
- Rose worked in both modeling and film production.
- She performed limited casting or production work before modeling internationally.
- IMDb combined data from two Rose Costas.
- A contributor attached family information to the wrong profile.
Without confirmation, the article should not select one theory as fact.
The appropriate wording is:
IMDb associates Rose Costa with several Brazilian screen projects, but reliable independent evidence does not confirm that those credits belong to James Marsden’s former girlfriend. IMDb
Rose Costa’s Early Life
Very little dependable information exists about Rose’s childhood.
Established publications confirm that she is Brazilian.
However, they do not provide a complete account of:
- Her hometown
- Parents
- Siblings
- Childhood interests
- Schools
- Religious background
- First modeling audition
- Immigration history
- Move to the United States
Generic biography pages often fill this gap with a precise birthplace and invented statements about her personality.
For example, a page may say she “always dreamed of fashion” or was “discovered at a young age.”
Such sentences sound natural in a biography, but they require evidence.
Rose has not published a widely available interview describing those experiences.
How Old Is Rose Costa?
Rose’s exact age is not confirmed by a sufficiently authoritative source.
Several celebrity databases publish March 9, 1988, as her birthday.
Based on that date, she would be 38 in 2026.
However, the date does not appear in the strongest established coverage reviewed for this article.
People, ABC News, and Page Six identify her professionally and document her family connection but do not publish her complete birth date.
Therefore, the quick-facts table should omit an exact age.
The appropriate answer is:
Rose Costa’s exact birth date and current age have not been reliably confirmed through an authoritative public biography.
Is March 9, 1988, Rose Costa’s Confirmed Birthday?
The date is widely repeated, but its original source remains unclear.
Famous Birthdays and multiple biography sites use it.
Repetition alone does not create independent verification.
Many sites copy structured information from one another.
Consequently, ten pages may appear to support a date even though they all depend on a single unreferenced entry.
A stronger confirmation would come from:
- Rose’s own birthday announcement
- A verified social-media post
- An agency biography
- A direct interview
- An official record
- Established contemporaneous reporting
Until such confirmation is available, the date should be described as reported but unverified.
Where Was Rose Costa Born?
Brazil is confirmed as her country of origin.
Some websites narrow the location to São Paulo.
Others do not identify a city.
No authoritative profile reviewed for this article clearly documents her specific birthplace.
Therefore, the quick-facts table should use Brazilian model rather than assigning São Paulo or another city.
What Is Rose Costa’s Full Name?
The names Rose Costa and Roseane Costa appear publicly.
People refers to her as Rose Costa.
Search indexing and Instagram material identify the account connected with her family posts as Roseane Costa.
Some generic biographies add further names, including Coelho or Ribeiro.
Those expanded versions lack dependable confirmation.
The article should therefore use:
- Rose Costa as the established public name
- Roseane Costa when discussing the social account
It should not publish a longer legal name without evidence.
What Is Known About Rose Costa’s Education?
No authoritative public biography confirms Rose’s school or university history.
A LinkedIn page using her name lists Universidade Federal de Minas Gerais.
Another generic biography claims she studied psychology elsewhere.
These claims conflict and lack sufficient independent confirmation.
There are also identity concerns because several Brazilian professionals share the name Rose Costa.
The appropriate conclusion is that her education remains private.
How Did Rose Costa Meet James Marsden?
The exact circumstances remain uncertain.
Entertainment reporting indicates that they became involved after James separated from Lisa Linde in 2011.
Several tabloids describe a brief meeting or relationship in Miami.
Other websites reduce it to a “one-night stand.”
Rose and James have not provided a detailed joint account explaining:
- When they first met
- Who introduced them
- How long they spent together
- Whether they formally dated
- How they defined the relationship
- When it ended
People used the restrained wording that they briefly dated.
That wording should guide the article.
It communicates the relationship without turning unverified tabloid details into established history
Who Is James Marsden?
James Marsden is an American actor whose career began during the 1990s.
He gained broad recognition as Scott Summers, also known as Cyclops, in the X-Men film series.
His other prominent projects include:
- The Notebook
- Superman Returns
- Hairspray
- Enchanted
- 27 Dresses
- Westworld
- Dead to Me
- Jury Duty
- Sonic the Hedgehog
James had two children, Jack and Mary, during his marriage to Lisa Linde.
He later welcomed William with Rose Costa.
Were Rose Costa and James Marsden Married?
No.
Rose and James were not publicly documented as husband and wife.
They were described as former partners or as having briefly dated.
William’s birth does not mean the parents married.
Numerous generic biographies incorrectly use terms such as:
- Husband
- Ex-husband
- Wife
- Divorce
- Former spouse
Those terms are misleading in this case.
The accurate description is:
James Marsden is Rose Costa’s former boyfriend and the father of her son.
How Long Did Rose and James Date?
The exact duration is not publicly established.
People described the relationship as brief.
Some tabloids characterize it as a single encounter, while other sites imply that they continued dating during the pregnancy.
Neither Rose nor James has published a detailed timeline.
Therefore, the article should not assign exact starting and ending dates.
The strongest conclusion is that the relationship was short and did not become a marriage or long-term public partnership.
Did Rose Costa Have an Affair?
Several low-quality websites claim that Rose was dating someone else when she became involved with James.
They identify a supposed boyfriend and describe private conversations as though a reporter witnessed them.
These claims require stronger evidence.
No direct interview with Rose, authenticated statement from the alleged former partner, or dependable legal record establishes the complete story.
The article should not accuse a living person of cheating based on copied celebrity gossip.
The responsible wording is:
Tabloid accounts have made claims about Rose’s relationship status at the time, but the details have not been reliably verified.
When Was William Luca Costa-Marsden Born?
William Luca Costa-Marsden was born on December 14, 2012, in Los Angeles.
People announced the birth five days later and identified Rose as a Brazilian model.
William became James Marsden’s third child and Rose’s first publicly documented child.
Who Is William Luca Costa-Marsden?
William is the son of Rose Costa and James Marsden.
He occasionally appears in public with his father and has attended premieres connected with the Sonic the Hedgehog films.
People’s updated profile reports that Rose has shared selected moments from William’s life, including travel and skiing.
However, he remains a minor.
A biography about his mother should therefore avoid unnecessary information about:
- His school
- Private address
- Daily schedule
- Friends
- Contact details
- Medical history
- Unverified social accounts
The relevant public facts are his parentage, birth date, and place within the Marsden family.
Does William Spend Time With Both Parents?
Public evidence indicates that both Rose and James are involved in William’s life.
Rose’s social posts show travel and family experiences with him.
James has brought William to film-related public events and includes him when discussing his three children.
However, the precise custody or parenting arrangement is private.
No dependable public document establishes:
- A custody percentage
- Support payments
- Residential schedules
- School-year arrangements
- Holiday divisions
- Legal disputes
Therefore, the article should not speculate about legal or financial details.
Who Are William’s Half-Siblings?
William has two older paternal half-siblings:
- Jack Marsden
- Mary James Marsden
James welcomed Jack and Mary during his marriage to Lisa Linde.
The three children have appeared together with their father at public events.
Online claims that William has never met his half-siblings are therefore incorrect.
Does Rose Costa Use Instagram?
Rose appears to maintain a public Instagram account under the name Roseane Costa.
Search indexing associates the handle @rose.ncosta with her.
More importantly, People links directly to posts from Rose while discussing William’s travel, skiing, and birthday.
This connection provides stronger authentication than a random name match.
However, the article should avoid calling the account “verified” unless Instagram displays an official verification badge.
The accurate wording is:
The public Instagram account cited in established coverage appears under Roseane Costa and is associated with the handle @rose.ncosta.
What Does Rose Share Online?
Public posts connected with Rose focus largely on:
- Travel
- Family moments
- Her son
- Lifestyle photographs
- Outdoor activities
- Food
- Personal celebrations
People reported that she described William as her travel companion and discussed the countries they had visited together.
She also shared posts about his skiing and birthday.
These posts provide limited insight into her current life.
However, social media does not establish every part of her biography.
A travel photo cannot verify:
- Net worth
- Property ownership
- Relationship status
- Agency contracts
- Permanent residence
- Annual income
Does Rose Costa Have an Official Website?
The domain rosecosta.com exists, but no dependable connection with the Brazilian model was established.
The name is shared by several artists, writers, designers, and professionals.
Therefore, publishers should not call the domain Rose’s official modeling website without a direct link from her recognized account or agency.
What Is Rose Costa Doing Today?
Rose keeps a relatively low public profile.
Her public social posts indicate that she has continued sharing family, travel, and lifestyle moments.
Nevertheless, established reporting does not document a current agency, major media venture, television career, product line, or publicly registered company.
The most accurate summary is that Rose appears focused on private life and parenting while maintaining a limited public social presence.
Where Does Rose Costa Live?
Her current home has not been reliably confirmed.
Older professional references connect her with Los Angeles or West Hollywood.
However, an old modeling location or LinkedIn location does not necessarily reflect her present residence.
Her international travel posts also should not be interpreted as permanent residence.
The article should not publish or attempt to infer a private home address.
Is Rose Costa Married?
No reliable current source confirms that she is married.
Numerous websites label her single, engaged, dating, or married.
Those descriptions often depend on unidentified social-media photographs rather than a direct announcement.
The safest answer is that her current relationship status remains private.
Did Rose Costa Date Skeet Ulrich?
Several celebrity websites claim that Rose had a relationship or engagement with actor Skeet Ulrich.
However, dependable reporting confirming that relationship was not located during this research.
The claim should not be included as a firm fact without an authenticated statement, established publication, or public appearance clearly identifying them as a couple.
Did Rose Costa Date Lloyd Klein?
Generic biographies also connect Rose with designer Lloyd Klein.
Again, the available claims largely circulate through celebrity databases and copied relationship lists.
Without stronger documentation, this should remain an unverified report rather than a central part of her biography.
Rose Costa’s Net Worth
Rose Costa’s personal net worth is not publicly verified.
The figure most often repeated online is $18 million.
However, the sites publishing that amount do not provide:
- Income statements
- Tax documents
- Property ownership records
- Investment portfolios
- Business valuations
- Agency contracts
- Modeling fees
- Debts
- Trust information
Some pages attempt to estimate her wealth by multiplying an alleged hourly model rate.
That calculation is unreliable.
Models are not necessarily paid one fixed rate for every hour of every year.
Agency commissions, expenses, taxes, unpaid test shoots, travel, contract terms, and inconsistent bookings can significantly affect income.
The accurate answer is:
Rose Costa’s net worth remains private, and the frequently repeated $18 million estimate is unsupported.
Is Rose Costa Wealthy Because of James Marsden?
The public does not know Rose and James’s private financial arrangements.
Having a child with a successful actor does not automatically establish a particular net worth.
The available record does not disclose:
- Child-support terms
- Property transfers
- Trusts
- Gifts
- Shared investments
- Legal settlements
Moreover, money provided for a child’s care is not automatically the parent’s personal wealth.
Therefore, James Marsden’s career earnings should not be assigned to Rose.
Is Rose Costa Dead?
No credible evidence indicates that the Brazilian model Rose Costa has died.
The obituary pages in the competitor set concern other women with the same name.
One Bedford obituary concerns a woman born in 1934 who lived in Massachusetts and was married to Dennis Costa.
Another memorial page concerns a Pennsylvania woman born in 1937.
Neither record concerns James Marsden’s former girlfriend.
Is the Rosa Costa Wikipedia Page About the Model?
No.
The page is about Rosa Costa Soler, a Spanish synchronized swimmer.
She was born in Palma de Mallorca in 1964 and competed at the 1984 Summer Olympics.
The model connected with James Marsden is Brazilian and belongs to a different generation.
Publishers should not use the swimmer’s:
- Birth date
- Height
- Nationality
- Olympic history
- Photograph
- Athletic record
in an article about Rose Costa the model.
Is the Rose Costa Artist Website Hers?
No reliable evidence establishes that the website belongs to the model.
The shared name creates a risk of combining unrelated careers.
Unless the website itself mentions Ford Models, James Marsden, William, or the public social account associated with Rose, it should not be used as her professional source.

Conclusion
Rose Costa is a Brazilian model whose name became widely known through her brief relationship with James Marsden.
She had a professional identity in modeling and was connected with Ford Models before and around the period when entertainment publications began covering her personal life.
Rose and James were not married.
They briefly dated after his separation from Lisa Linde and later welcomed a son, William Luca Costa-Marsden.
William was born in Los Angeles on December 14, 2012.
He is James’s third child and Rose’s only publicly documented child.
Public evidence indicates that both parents remain part of William’s life.
Rose has shared selected travel, birthday, and family moments, while James has appeared with William at premieres and discussed all three of his children in interviews.
However, their exact parenting and financial arrangements remain private.
Rose also appears to maintain a public Instagram presence under the name Roseane Costa.
People links directly to several of her family posts, providing stronger authentication than generic profile directories.
Nevertheless, the account should not be described as formally verified unless the platform displays that status.
Many other details repeated about Rose remain uncertain.
Strong sources do not confirm her precise birthday, current age, birthplace, full legal name, education, height, present modeling agency, current partner, residence, or net worth.
The claim that she is worth $18 million has no visible financial foundation.
Likewise, articles should not assume that the luxury brands listed on biography pages were official modeling clients.
The competitor set also demonstrates why identity verification matters.
The Rosa Costa Wikipedia page belongs to a Spanish Olympic synchronized swimmer.
The funeral-home pages concern deceased American women born decades before the model.
The website www.rosecosta.com has not been authenticated as the model’s official site.
Finally, the IMDb page may contain a mixture of family information and Brazilian production credits that have not been independently connected with James Marsden’s former girlfriend.
