Milaine Desaulniers is best known as the younger sister of Oscar winning actress Brie Larson, whose birth name is Brianne Sidonie Desaulniers. Unlike her famous sister, Milaine has largely stayed away from Hollywood and public attention. Her story has nevertheless attracted interest because of her connection to one of the entertainment industry’s most recognizable actresses.
Public records and biographical sources identify Milaine as the daughter of Sylvain and Heather Desaulniers and the younger sister of Brie Larson. She was born on January 5, 1993, and grew up during a period when her family experienced major changes, including her parents’ separation and a move from Sacramento to Los Angeles.

IMDb specifically identifies Raya Milaine Desaulniers as Brie Larson’s younger sister and lists her birth date as January 5, 1993. Some secondary websites use slightly different descriptions of her professional life, so career information should be treated with appropriate caution.
Milaine Desaulniers Early Life and Background
Milaine Desaulniers was born in Sacramento, California, into the family of Sylvain and Heather Desaulniers. Her older sister, Brie Larson, was born in 1989, making the sisters roughly three years apart. Their early childhood was shaped by their parents’ work in chiropractic care and by the family’s eventual separation.
According to biographical accounts about Brie Larson’s family, Milaine and Brie experienced significant financial and family challenges after their parents separated. Their mother became the primary parent in the household, and the family later moved to Los Angeles as Brie pursued acting opportunities. This period became an important part of the sisters’ shared childhood.
Milaine Desaulniers Age and Body Details
Milaine Desaulniers was born on January 5, 1993, making her 33 years old in 2026. Her birth date is one of the more consistently reported details about her, with IMDb specifically listing January 5, 1993.
| Age and Appearance Detail | Information |
| Date of Birth | January 5, 1993 |
| Age in 2026 | 33 |
| Birthplace | Sacramento, California |
| Height | Not reliably confirmed |
| Weight | Not publicly confirmed |
| Eye Color | Not reliably documented |
| Hair Color | Not reliably documented |
There is limited trustworthy information about Milaine’s height, weight or other physical measurements. Because she is not a mainstream celebrity, repeating unsupported body measurements would add little value and could create inaccurate information.
Parents and Family Background
Milaine is the daughter of Sylvain Desaulniers and Heather Desaulniers. Her family background has received attention largely because of Brie Larson’s public career. Both parents were associated with chiropractic work, and their relationship later ended in divorce.
| Family Member | Relationship | Publicly Known Information |
| Sylvain Desaulniers | Father | Worked as a chiropractor |
| Heather Desaulniers | Mother | Worked in chiropractic care |
| Brie Larson | Older Sister | Oscar winning actress |
| Milaine Desaulniers | Herself | Younger daughter in the family |
The family separation became particularly important in Brie Larson’s childhood. Public interviews and biographical accounts have described the difficulties surrounding the divorce and the family’s move to Los Angeles. Milaine experienced those changes alongside her sister.
Sylvain Desaulniers
Sylvain Desaulniers is known publicly as Brie Larson and Milaine Desaulniers’ father. Sources identify him as a chiropractor, and reports about the family describe him and Heather as having worked in chiropractic care before their marriage ended.
Heather Desaulniers
Heather Desaulniers, formerly Heather Edwards, is Milaine and Brie’s mother. After the divorce, Heather raised the two girls as a single mother while supporting Brie’s developing interest in acting. Her role became especially important during the family’s transition from Sacramento to Los Angeles.
Her Famous Sister
Milaine’s older sister is Brie Larson, born Brianne Sidonie Desaulniers on October 1, 1989. Brie began acting as a child and eventually became one of Hollywood’s most successful actresses. Her breakthrough performance in Room earned her the Academy Award for Best Actress, while her role as Carol Danvers in Marvel’s Captain Marvel made her a global star.
Brie’s success naturally brought greater attention to her family, including Milaine. However, Milaine has not pursued the same level of public recognition. Her comparatively private lifestyle makes her an interesting contrast to her sister’s highly visible career.

Parents’ Separation and Its Effect
The separation of Milaine’s parents was a major turning point for the family. Brie was around seven years old when her parents divorced, while Milaine was still very young. After the separation, Heather became the primary caregiver and moved with her daughters to Los Angeles.
The family reportedly faced financial difficulties during this period. Accounts of Brie’s childhood describe a modest living situation and the challenges of supporting two children while pursuing opportunities in a new city. These experiences help explain why the sisters developed such a close bond.
Life in Los Angeles and Early Hard Times
Moving to Los Angeles changed the direction of the Desaulniers family. Brie was interested in acting from a young age, and Los Angeles offered greater opportunities for auditions and professional work. Milaine therefore grew up in an environment where her sister’s acting ambitions were becoming increasingly important to the family.
Secondary accounts describe the family living in limited circumstances after arriving in Los Angeles. Rather than enjoying the glamorous lifestyle often associated with Hollywood, the sisters reportedly experienced a much more ordinary and financially difficult childhood. That background provides important context for their later lives.
Close Relationship With Her Sister
Milaine and Brie have reportedly remained close despite taking very different professional paths. Their childhood experiences created a shared connection that continued into adulthood.
One memorable example involves gaming. Public accounts have described the sisters bonding over Animal Crossing, a hobby that gave them a simple way to spend time together away from the pressures surrounding Brie’s acting career. Milaine’s connection with gaming is particularly interesting because Brie herself has publicly discussed being an avid gamer.
Simple Childhood Fun and Video Games
The sisters’ childhood was not defined entirely by financial or family difficulties. Accounts about their relationship also highlight ordinary activities that helped them stay connected. Video games became one of those shared interests.
Animal Crossing has been mentioned in coverage about the sisters as an activity they enjoyed together. This detail adds a more personal dimension to Milaine’s story because it shows their relationship beyond red carpets and Hollywood events.
Work as a Mathematics Teacher
One of the most frequently reported details about Milaine’s professional life is her work in education. Several secondary sources describe her as a mathematics teacher, and public employment records have been cited in connection with the name Raya Milaine Desaulniers.
However, this is an area where careful wording matters. Public payroll information is not the same as a personal interview or official biography, so it is safer to describe the teaching career as reported public information rather than claim that every employment detail has been personally confirmed by Milaine.
If the reported records refer to Brie Larson’s sister, her career represents a striking contrast with Brie’s Hollywood path. Teaching mathematics offers a stable and community focused profession far removed from celebrity culture.
Creative Interests and Small Projects
Although education appears to be an important part of Milaine’s reported professional identity, some entertainment databases and secondary websites have also connected her name with small creative projects. These references are much less extensive than her sister’s acting credits.
Some recent biography sites describe Milaine as having limited screen or creative involvement, but the available evidence is not strong enough to characterize her as a major actress or filmmaker. The more reliable picture is of someone whose public identity has remained centered on family connections and a private professional life.
Public Appearance at the 91st Academy Awards
One of Milaine’s most visible public appearances came at the 91st Academy Awards in 2019, when she attended with Brie Larson. The event was significant because Brie was already an established Academy Award winner and Marvel star, while Milaine generally stayed outside the entertainment spotlight. Secondary reporting and image archives identify the sisters together at the event.
The appearance generated interest because it offered fans a rare public glimpse of Brie Larson’s younger sister. It also reinforced the close family relationship that has been reported between the two women.
Where Milaine Desaulniers Is Today
As of 2026, Milaine Desaulniers remains a relatively private figure. She does not have the extensive public profile associated with Brie Larson, and there is limited verified information about her current personal life.
| Current Life Detail | Public Information |
| Current Age | 33 |
| Location | California, according to secondary reports |
| Career | Mathematics teaching is widely reported |
| Entertainment Work | Limited and inconsistently documented |
| Relationship Status | Not publicly confirmed |
| Children | No verified public information |
| Social Media | No major verified public profile |
| Public Appearances | Rare |
Her limited public presence appears intentional. Rather than building a career around celebrity, Milaine has maintained a much quieter identity while remaining connected to her sister and family.
Why She Chose a Private Life
There is no widely documented interview in which Milaine explains why she prefers privacy. It is therefore better not to assign a specific motivation to her decision.
Her lifestyle can, however, be understood in contrast with Brie Larson’s career. Brie entered entertainment as a child and eventually became an Oscar winning actress and Marvel star. Milaine did not follow that path and has instead been associated with education and a comparatively ordinary professional life.
That difference is one of the most interesting parts of Milaine Desaulniers’ story. Being related to a famous actress does not necessarily mean wanting fame personally.
Income and Financial Details
Milaine Desaulniers’ personal income and net worth have not been reliably disclosed. Some celebrity biography websites publish estimated figures, but these estimates generally lack financial documentation and should not be treated as confirmed facts.
| Financial Detail | Information |
| Primary Reported Profession | Mathematics Teacher |
| Salary | Not publicly verified |
| Net Worth | Not publicly disclosed |
| Business Ownership | No reliably confirmed major business |
| Financial Status | Private |
Her reported career in education provides a more credible explanation of her professional identity than speculative net worth figures. There is also no reliable evidence that her financial situation should be inferred from Brie Larson’s wealth or Hollywood success.

Yet Milaine appears to have chosen a quieter direction, with education and family life receiving far more attention than Hollywood.

Today, many details about Milaine’s personal life remain private, and that privacy should be respected while distinguishing confirmed facts from online speculation.
