Who Is Milaine Desaulniers?
Milaine Desaulniers, whose fuller name is reported as Raya Milaine Desaulniers, is an American educator with connections to a small number of entertainment projects. She has also been credited professionally under the name Mimsy Desaulniers.
She attracts public interest mainly because she is Brie Larson’s younger sister. IMDb’s biography for Mimsy Desaulniers identifies her as Larson’s sister and connects her with several creative projects.
Unlike her famous sister, Milaine has largely chosen to keep her personal life away from interviews, celebrity media and regular red-carpet appearances.
Age and Birthday
Several biographical sources report that Milaine Desaulniers was born on January 5, 1993, which would make her 33 years old in 2026. The reported birthplace is Sacramento, California.
Her exact birthday is not as strongly documented as her sister’s birth information, so it is better described as widely reported rather than officially confirmed by Milaine herself.
Her sister, Brie Larson, was born on October 1, 1989, under the name Brianne Sidonie Desaulniers.
Early Life
Milaine grew up in a family whose background was far removed from traditional Hollywood circles. Her parents are Heather and Sylvain Desaulniers, who have been publicly described in biographies of Brie Larson as chiropractors.
Larson’s documented childhood involved significant family changes. After her parents separated, she moved with her mother and younger sister. Milaine therefore spent part of her childhood alongside Brie during the period when the future actress was beginning to explore acting.
Despite eventually becoming connected to a famous Hollywood family, Milaine appears to have preferred a more private professional directiily
The Desaulniers family includes Milaine, Brie Larson, Heather Desaulniers and Sylvain Desaulniers. Public accounts identify Milaine as the younger of the two daughters.
Brie Larson’s birth name is Brianne Sidonie Desaulniers, meaning Larson is a professional surname rather than the family’s original surname. Biographical records about Larson identify Milaine as her sister and Heather and Sylvain as their parents.
Although the sisters followed very different careers, their occasional public appearances together suggest that they have remained connected despite Brie’s demanding entertainment career.
Relationship With Brie Larson
Milaine’s relationship with Brie Larson is one of the main reasons people search for her biography. Brie became internationally recognized after performances in films such as Room, Captain Marvel, Short Term 12 and Kong: Skull Island.
Milaine has occasionally supported her sister publicly but has never attempted to build a similar celebrity profile.
One of their most notable appearances together came during the 91st Academy Awards in February 2019, when Milaine accompanied Brie at the Hollywood ceremony. The appearance remains one of the clearest examples of Milaine stepping into the public spotlight.
Career
Milaine Desaulniers appears to have built her main professional career in education rather than entertainment.
Public payroll records list Raya Milaine Desaulniers as a teacher at William S. Hart Union High in California. Records show her employment in the district across multiple years, including 2017 and 2021, with later listings extending through 2024.
Other published profiles describe her specifically as a mathematics teacher. Her career therefore provides an interesting contrast to her sister’s highly public life in film.
Acting Work
Although teaching became her more established profession, Milaine has some genuine entertainment credits.
Under the name Mimsy Desaulniers, she appeared as Genevieve in the short film The Arm. The film was directed by Brie Larson, Jessie Ennis and Sarah Ramos. IMDb confirms both Milaine’s role and the directing team.
The project also received a Special Jury Prize for Comedic Storytelling at the 2012 Sundance Film Festival.
IMDb additionally connects Mimsy with The Dew Project and Releasing My First Short Film, Warning: Childhood Cringe.
Net Worth
There is no trustworthy public figure for Milaine Desaulniers’ net worth.
Some celebrity websites provide estimated amounts, but those figures are not supported by financial disclosures, business records or statements from Milaine. For that reason, attaching a precise dollar amount to her wealth would be misleading.
Public employment records do provide evidence of her earnings as a teacher. For example, records for 2021 list regular pay of about $61,807, with additional compensation and benefits reported separately.
That salary information should not be confused with net worth, which remains private and unconfirmed.
Height and Appearance
Milaine Desaulniers’ exact height and body measurements have not been reliably documented by a strong public source.
Several entertainment blogs publish specific measurements, but there is little evidence showing where those numbers originated. A responsible profile should therefore list her height as not publicly confirmed.
Photographs from public appearances show her with a natural and understated style. However, physical details such as precise weight, measurements or other personal statistics should not be presented as established facts without reliable sourcing.
Personal Life
Milaine has successfully kept her romantic and family life private.
There is no dependable public confirmation of a husband, boyfriend, marriage or children. Because she is not a full-time public figure, very little information about her relationships has entered reliable media coverage.
Her privacy is one of the strongest contrasts between Milaine and Brie Larson. While Brie regularly participates in interviews, premieres and promotional appearances, Milaine appears to prefer a life centered on her career and personal circle.
Social Media
Milaine Desaulniers does not appear to maintain a major verified public social-media presence under her full name.
Various websites have linked possible Instagram usernames to her, but those profiles have not been sufficiently verified to treat them as official accounts. There is similarly no widely recognized verified TikTok, Facebook, X or YouTube profile belonging to her.
This limited online presence fits with the broader picture of someone who has chosen to remain largely outside celebrity culture.
Lifestyle
Milaine’s publicly documented career suggests a low-profile and professionally focused lifestyle.
Instead of developing a personal brand around her connection to Brie Larson, she appears to have invested much of her professional life in teaching. Her entertainment work has remained limited and occasional.
There is no reliable information confirming luxury homes, expensive cars or extravagant spending. Claims about these subjects should therefore be avoided unless supported by credible records.
Interesting Facts
One interesting detail about Milaine is that she has used Mimsy Desaulniers in entertainment credits while public employment records identify her as Raya Milaine Desaulniers.
She has also managed to maintain a recognizable connection to Hollywood without becoming a conventional celebrity herself. Her appearance in The Arm links her creatively with Brie Larson, while her long-running teaching record shows that her primary professional identity developed elsewhere.
Her story shows two very different career paths within the same family: one built in international film and the other largely in education.
Life Away From Fame
Milaine Desaulniers is more than simply Brie Larson’s sister. Available records portray her as an educator with a small creative background who has deliberately maintained a private public image.
Some details commonly searched online—including her reported 1993 birth date—are available but not equally well documented. Meanwhile, her height, net worth, relationship status and personal social accounts remain unconfirmed.
What can be established more confidently is her family connection to Brie Larson, her teaching career and her involvement in projects such as The Arm. Together, these details provide a more balanced picture of Milaine without filling the gaps in her private life with speculation.
