Quick Bio

Her career has included fashion modeling, photoshoots, brand-related projects, and entrepreneurial activities. She joined Ford Models in 2006, giving her an opportunity to develop her career within the competitive international fashion industry.

Outside modeling, Rose has explored business and creative projects. She co-founded the online clothing brand L’Faroe and has also been associated with behind-the-scenes work on film projects such as Estômago: A Gastronomic Story and Luz.

Her personal life changed significantly after becoming a mother. Rose and James Marsden welcomed their son, William Luca Costa-Marsden, in December 2012. Since then, motherhood has remained an important part of her life.

Rose Costa’s Early Life and Brazilian Background

Rose Costa was born on March 9, 1988, in Brazil. Her Brazilian background remained part of her identity even after her modeling career introduced her to an international lifestyle involving fashion, travel, and different cultures.

She spent her younger years surrounded by family before entering the modeling industry. Her childhood remained relatively private as her public recognition developed primarily through her adult career and later relationships rather than her early years.

Family has continued to hold an important place in Rose’s life. She shared a loving relationship with her father, whose death deeply affected her. Her emotional messages about missing him reflected their meaningful father-daughter connection.

Rose also shares a close relationship with her brother. Despite developing an international career and becoming connected with Hollywood, she has continued showing affection for her family and maintaining ties to her personal roots.

Rose Costa’s Age and Birthday

Rose Costa was born on March 9, 1988. She turned 38 years old in March 2026. Her birthday falls under Pisces, the final astrological sign in the traditional Western zodiac calendar.

Her life has changed considerably since her younger modeling years. She entered professional fashion as a young woman before experiencing greater recognition through her career, relationships, business interests, and eventual journey into motherhood.

Becoming older has also brought different priorities into Rose’s life. Fashion remains part of her story, but raising William and developing a peaceful personal lifestyle have become equally important aspects of her everyday world.

At 38, Rose represents more than the young model once connected with a Hollywood celebrity. Her journey now combines years of professional experience with entrepreneurship, family responsibilities, travel, creativity, and motherhood.

Rose Costa’s Height and Physical Appearance

Rose Costa stands approximately 5 feet 9 inches, or 1.75 meters, tall. Her height and naturally elegant appearance helped her develop a professional career within an industry where physical presentation plays an important role.

Her weight has been listed at approximately 63 kilograms. Rose maintains a slim and fit appearance, complementing the polished image she developed during her years working professionally within fashion and modeling environments.

She has brown hair and hazel eyes. Combined with her tall frame and confident presentation, these features contributed to the distinctive appearance that helped her work successfully on different modeling and fashion-related assignments.

Rose has continued maintaining an active and healthy-looking lifestyle after motherhood. Her appearance reflects her longtime connection with fashion, while her confidence and personal presentation remain recognizable parts of her public image.

How Rose Costa Started Her Modeling Career

Rose Costa began developing her modeling career when she was relatively young. A major professional milestone arrived in 2006 when she joined Ford Models, an established modeling agency representing talent within the fashion industry.

Working with a major agency provided opportunities to participate in professional photoshoots and fashion projects. Rose’s distinctive appearance and tall frame suited modeling, helping her establish an identity within the competitive fashion business.

Her modeling work also introduced an international dimension to her lifestyle. Fashion-related opportunities allowed her to travel and experience different places while continuing to develop confidence and professional experience within her chosen career.

This background is important because Rose had professional ambitions beyond her later celebrity relationship. Modeling became one of the foundations of her adult life and eventually helped lead toward her interests in fashion entrepreneurship.

Rose Costa’s Business and Creative Work

Fashion eventually became more than modeling for Rose Costa. She expanded her interests into entrepreneurship by co-founding L’Faroe, an online clothing brand built around fashionable pieces and a combination of contemporary and vintage-inspired ideas.

The business allowed Rose to use her experience differently. Instead of participating only as a model, she could explore the creative and commercial side of clothing while developing something connected with her personal interest in fashion.

Rose has also explored work connected with film. Her creative experience included behind-the-scenes involvement with projects such as Estômago: A Gastronomic Story and Luz, adding another dimension to her professional background.

These different activities demonstrate the variety within Rose’s career. Modeling remains her best-known professional field, but fashion entrepreneurship and creative projects allowed her to expand beyond the traditional boundaries of a modeling career.

How Did Rose Costa and James Marsden Meet?

Rose Costa and James Marsden became romantically connected in 2011. Their paths crossed in Miami during a significant period in Marsden’s personal life following the end of his marriage to actress Lisa Linde.

Their romantic connection was relatively brief rather than a traditional long-term relationship. Nevertheless, what initially appeared to be a short romance eventually created a permanent family connection between Rose and the Hollywood actor.

Marsden was already widely recognized through his successful acting career, including his role as Cyclops in the X-Men film franchise. Consequently, public interest surrounding Rose increased considerably once their relationship became known.

The attention introduced Rose to audiences outside the fashion world. Although their romantic relationship did not develop into marriage, their story took an important turn after Rose discovered she was expecting their child.

Rose Costa’s Relationship Drama and Chris Santos

Rose Costa’s relationship history attracted additional attention because she had also been romantically linked with actor and chef Chris Santos. Her connection with James Marsden therefore became surrounded by considerable discussion about their personal circumstances.

Rose and Chris had reportedly been together before her encounter with Marsden. The unexpected development involving the Hollywood actor consequently created a complicated romantic situation that attracted significant attention at the time.

For Rose, the experience represented a major transition in her personal life. What began as a brief encounter soon became far more significant after she learned that she was pregnant with James Marsden’s child.

The resulting attention made Rose considerably more recognizable beyond professional modeling circles. However, the lasting importance of that period was not the surrounding relationship drama but the arrival of her son and her transition into motherhood.

Rose Costa and James Marsden’s Son

Rose Costa became a mother in December 2012 when she welcomed William Luca Costa-Marsden. William is the son she shares with James Marsden and represents the lasting family connection created by their short romantic relationship.

Becoming a mother introduced a completely different responsibility into Rose’s life. Her priorities expanded beyond modeling, fashion, travel, and professional opportunities as raising William became an important part of her everyday world.

Rose has shared moments involving her son while maintaining a balance around their personal life. Their experiences together have included traveling as well as ordinary mother-and-son activities away from professional commitments and public attention.

William also shares an important connection with his father. Although Rose and James did not build a lasting romantic partnership, their son permanently connected their families and became the central focus of their relationship as parents.

Rose Costa and James Marsden’s Co-Parenting

Rose Costa and James Marsden did not remain romantically involved, but parenthood required them to maintain an ongoing relationship. Their connection consequently developed from a short romance into a long-term co-parenting arrangement centered around William.

Both parents have remained involved in their son’s life. Their ability to spend time with William demonstrates how two people can continue sharing parental responsibilities even when their original romantic relationship has already ended.

James Marsden is also a father to children from his previous marriage. Fatherhood therefore represents an established and important part of his personal life, with William maintaining his place within Marsden’s wider family.

For Rose, co-parenting allows her son to maintain meaningful relationships with both parents. Her connection with James today is consequently better understood through their shared responsibilities toward William rather than through their brief romantic history.

Rose Costa’s Relationships After James Marsden

Rose Costa continued her personal life after her romantic connection with James Marsden ended. Over subsequent years, she was associated with other men while continuing to balance relationships with motherhood and her professional interests.

One person linked romantically with Rose was actor Skeet Ulrich. The two appeared together and attracted attention as a couple, although their relationship ultimately ended without developing into a permanent partnership or marriage.

Rose was additionally connected with fashion designer Lloyd David Klein. Like her relationship with Ulrich, this connection eventually ended, leaving Rose free to concentrate on other aspects of her personal and professional life.

In 2026, Rose is described as single. Rather than being defined by a current romantic partner, her present life primarily revolves around motherhood, personal interests, fashion, business activities, travel, and maintaining her independence.

Rose Costa’s Net Worth

Rose Costa’s net worth has been estimated at approximately $18 million. Her financial position has been associated with her years of modeling, fashion-related activities, entrepreneurial interests, and other professional projects developed throughout her career.

Modeling provided the earliest major foundation for her professional earnings. Joining Ford Models gave her access to fashion opportunities, photoshoots, brand-related assignments, and an international working environment while she was still relatively young.

Her involvement with L’Faroe expanded her professional identity into business. Entrepreneurship provided another avenue through which Rose could use her understanding of fashion rather than relying exclusively on work as a professional model.

Rose’s lifestyle combines comfort with personal interests such as traveling and spending time with William. Her story reflects a career that developed across modeling and fashion while gradually expanding toward business, creative work, and family life.

Rose Costa’s Lifestyle and Interests

Travel has been a noticeable part of Rose Costa’s lifestyle. Her modeling background naturally introduced her to international experiences, and traveling continued becoming part of her life as both professional opportunities and personal adventures developed.

Motherhood changed the way some of these experiences looked. William became an important companion in her life, and Rose has enjoyed spending time with him while balancing family responsibilities with her individual interests and work.

She also has an interest in healthy living and cooking. Maintaining an active lifestyle complements her background as a professional model, while food and everyday wellness provide a more personal side beyond fashion-related appearances.

Rose’s lifestyle today appears centered on balance. Rather than continuously seeking celebrity attention, she combines motherhood, travel, creativity, fashion, business, family relationships, and personal time within a comparatively private everyday life.

Rose Costa on Instagram

Instagram provides Rose Costa with a way to share selected parts of her personal world. Her social media presence includes glimpses of travel, family experiences, lifestyle moments, fashion, and her relationship with her son.

She nevertheless maintains boundaries around what she shares publicly. Rose does not present every part of her personal life online, allowing her to maintain privacy despite the attention created by her celebrity connections.

Some of her more personal posts have reflected her family relationships. Her messages concerning her late father, for example, showed the emotional importance he continued to hold in her life following his death.

Her online presence therefore presents several sides of her personality. Followers can see her as a model and fashion-oriented woman while also observing selected moments reflecting motherhood, family connections, travel, and everyday experiences.

Rose Costa’s Life in 2026

By 2026, Rose Costa is 38 years old and has moved far beyond the period when her relationship with James Marsden first attracted attention. Her priorities increasingly center around family and personal development.

Motherhood remains one of the defining elements of her current life. William is now growing older, but Rose continues maintaining a strong relationship with him while sharing parenting responsibilities with his father.

Her professional story also remains connected with modeling, fashion, business, and creativity. These interests demonstrate that her identity developed independently from the Hollywood relationship that initially introduced her name to a much wider audience.

Rose’s journey has included professional success, complicated relationships, motherhood, entrepreneurship, loss, and personal growth. In 2026, she represents a woman whose story extends well beyond being remembered simply as James Marsden’s former partner.

Final Thoughts

Rose Costa first entered professional life through modeling and established an international fashion background. Her association with Ford Models and later involvement in clothing entrepreneurship helped create an identity based around fashion, creativity, and independence.

Her brief relationship with James Marsden became the most publicly discussed chapter of her personal life. Although their romance ended, it resulted in something permanent when they welcomed their son, William Luca Costa-Marsden, in 2012.

Motherhood subsequently became central to Rose’s story. She and Marsden continued their connection as co-parents, while Rose balanced raising their son with her professional interests, relationships, family bonds, travel, and personal development.
