Milaine Desaulniers: The Sister Who Chose the Classroom Over the Red Carpet

The bed folded out of the wall. Three of them shared it — a mother, a seven-year-old with enormous acting ambitions, and a toddler who had no idea any of this was unusual. They ate ramen. They ate 99-cent tacos from Jack in the Box. They couldn’t afford a McDonald’s Happy Meal. And Brie Larson, who would one day win the Academy Award for Best Actress, later said she never remembered it as a hard time. My mom created this amazing world, she told Variety. It didn’t feel sparse.

The toddler in that one-room Los Angeles apartment was Milaine Desaulniers. She grew up in the same financial struggle, the same tight quarters, the same single-parent household that shaped her famous older sister — and then chose a life that looks almost nothing like hers. No Oscar. No Marvel franchise. No red carpet. Just a mathematics classroom in Santa Clarita, California, and a quiet life lived entirely on her own terms.

That’s not a lesser story. It might actually be the more interesting one.

Early Life: Sacramento, French, and a Shared Childhood

Milaine Desaulniers was born on January 5, 1993, in Sacramento, California — the second daughter of Heather and Sylvain Desaulniers, who ran a homeopathic chiropractic practice together. Her father, Sylvain, is Franco-Manitoban — French-Canadian from Manitoba — which is why the family surname sounds the way it does and why French was actually Brie’s first language as a young child. Their household was grounded in natural healing, alternative medicine, and the kind of quiet Northern California life that doesn’t make headlines.

Milaine was only about two years old when her parents separated. She and Brie were raised from that point almost entirely by their mother, Heather. The divorce was quiet, at least from the outside, but the effects were not. When Brie later talked publicly about their father, she described a slow realisation that a planned three-week trip to Los Angeles for one of her auditions had quietly become a permanent relocation — and that right before the family left Sacramento, their father had asked their mother for a divorce. Brie recalled waking one night to find her mother holding a hand over her mouth, trying not to cry loud enough to wake the girls.

Milaine doesn’t talk about any of this publicly. She never has.

What she and Brie have both acknowledged is the closeness forged in that tiny Los Angeles apartment — the fold-out Murphy bed, the ramen dinners, the warmth their mother built inside a space that offered almost none of the stability they’d left behind in Sacramento.

The Turning Point: From Sacramento to a One-Room LA Life

The move to Los Angeles was supposed to be temporary. Heather packed up her two daughters and found a one-bedroom studio apartment where the bed came out of the wall. The three of them shared it. Brie was seven. Milaine was barely a toddler. Money was very tight — there were ramen packets and 99-cent tacos and, as Brie later told Variety, no toys and two pairs of jeans between them.

But Heather, by all accounts, made it work in ways that money couldn’t measure. She filled the small space with imagination and routine. She used the family’s Nintendo GameCube as a reward system — finish the homework, earn the game time — which is how both sisters became devoted fans of Animal Crossing. That game became their thing. Their shared world inside a world that was otherwise uncertain and small.

Brie went on auditions. Milaine went along. While her older sister was already performing on The Tonight Show with Jay Leno at nine years old and signing a recording contract at thirteen, Milaine was simply the quiet sibling in the waiting room — watching, absorbing, present.

The two were largely homeschooled, which gave their education an unconventional shape. Brie graduated high school at fifteen. The flexibility of homeschooling allowed Brie to keep auditioning; it also meant Milaine came of age outside a traditional classroom — which makes her eventual choice to spend her adult life in one all the more interesting.

She grew up without walls and chose to build some, for other people’s children.

Career: A Classroom in Santa Clarita

Milaine Desaulniers is a mathematics teacher. That’s not a placeholder sentence or a vague summary — it’s the specific, verifiable center of her adult life. Public payroll records filed with the state of California confirm that a “Raya Milaine Desaulniers” has been employed as a teacher at the William S. Hart Union High School District in Santa Clarita, California, with records dating back to at least 2016.

The salary progression tells its own story. In 2017, her reported pay was $52,497. By 2020 it had risen to $60,606. By 2022, it reached $68,749. These are the numbers of a career teacher building steady seniority in a public school district — not supplemental income, not a side project. This is her work.

William S. Hart Union High School District serves the Santa Clarita Valley, a community of roughly 300,000 people in the northern outskirts of Los Angeles County. It’s a real district, with real students, and Milaine has been in it for the better part of a decade.

She has also dipped into creative work, quietly, under the nickname “Mimsy Desaulniers.” Her IMDb page — small, sparse, uncelebrated — credits her in three short films: The Arm (2012), The Dew Project (2021), and Warning: Childhood Cringe (2021). The Dew Project was directed by Brie Larson. Warning: Childhood Cringe appears to be a self-referential short that released the same year. None of these are commercial releases. All of them look like a person with a creative streak indulging it on her own schedule, away from any expectation of a career.

She’s a teacher who makes short films sometimes. That’s a complete life.

Personal Life: Bonds, Video Games, and a Father’s Complicated Shadow

Milaine has never given an interview. She has no confirmed social media presence — no Instagram, no TikTok, no X account, nothing. Almost everything known about her personal relationships comes through what Brie has said publicly over the years.

What Brie has said is consistent: they’re close. Genuinely, durably close, the kind of close that survives two people taking completely opposite paths through life. When COVID-19 lockdowns hit in 2020 and they couldn’t be in the same room, they reconnected through Animal Crossing: New Horizons — the same franchise they’d played on their mother’s GameCube as kids. Same game, different console, twenty-something years later.

Their relationship with their father, Sylvain Desaulniers, is more complicated. Brie has spoken publicly about being estranged from him for years — about feeling, after watching herself in Room, that he was the reason she’d always been drawn to volatile, damaged characters. Milaine has said nothing about this publicly. Sylvain, for his part, has disputed the estrangement narrative in interviews, saying he kept photos of both daughters and watched Room three times. It’s my daughter, and I love her to death, he said. This is her life, this is her thing.

Whatever the truth of their relationship with Sylvain, Milaine has kept it to herself. She wasn’t obligated to share it. She chose not to.

There is no confirmed information about Milaine’s romantic life, marital status, or whether she has children. Any sources claiming specific details about her relationships are speculating. She hasn’t shared any of it.

Her most notable public moment was on February 24, 2019 — the night of the 91st Academy Awards. Brie brought her as her date. Milaine walked the red carpet at the Dolby Theatre in Hollywood, California, in a gown, beside her sister, photographed for outlets and wire services across the world. She looked poised and happy. Then she went back to her classroom.

Controversies: A Note on Misinformation

There is very little genuine controversy in Milaine Desaulniers’ life — but there is a meaningful amount of misinformation worth addressing directly.

Several low-quality websites describe a “Milaine Desaulniers” who is a Canadian social media influencer born in 1998 in Montreal, with millions of TikTok followers and brand deals with Adidas. This is not the same person — or more likely, it is not a real person at all, but a fabricated profile built around the name. Another site describes her as a visual artist and sculptor born in 1990 in a small town. Also not supported by any verified record.

The real Milaine Desaulniers is a California-born schoolteacher with French-Canadian heritage, public payroll records, a handful of short film credits, and no social media presence. That’s what the verifiable record contains.

One source (detectmind.com) describes her as a growing actress who has “starred in multiple films.” This is an exaggeration of her three minor short film credits and should not be taken at face value. Her IMDb page as “Mimsy Desaulniers” lists three titles — all small, all independent, none mainstream.

When a private person becomes the subject of internet curiosity, the gap between what’s real and what’s invented tends to grow fast.

Current Life: Still in the Classroom, Still Out of the Frame

As of 2026, Milaine Desaulniers is thirty-three years old. She teaches mathematics at the William S. Hart Union High School District in Santa Clarita, California. She remains off social media. She doesn’t appear at industry events. She keeps the shape of her daily life — who she lives with, what she does on weekends, what she values most — entirely private.

Her sister Brie continues working: The Marvels (2023), ongoing projects, continued public life. Their bond, by every public account, remains intact. The dynamic seems to be one of genuine mutual respect rather than awkward distance — two people who went very different directions and stayed close anyway.

Heather Desaulniers, their mother, has remained present in both daughters’ lives. She joined Brie on stage during a Saturday Night Live monologue. She appeared at Brie’s Room premiere in 2015. She’s the thread the family kept pulling through everything.

Milaine isn’t chasing anything. She already found it.

Legacy: What It Means to Choose This Way

Legacy is a word that usually goes with fame. With awards, with films, with names that persist. Milaine Desaulniers has none of those things — and she doesn’t appear to want them.

What she has instead is a classroom full of teenagers who are learning mathematics from someone who grew up in a one-room apartment eating ramen while her older sister auditioned for commercials. She has a career she chose deliberately, built over nearly a decade, in a public school district that serves a real community. She has a sister who describes her as one of the most important people in her life.

That’s not a background story. That’s a life.

There’s something worth sitting with in the contrast between the Desaulniers sisters. Two children of the same divorce, the same Murphy bed, the same tight budget. One of them became Captain Marvel. The other became a math teacher. Both of them, by every available account, turned out all right.

The sister who never chased the spotlight might be the one living closest to the light.

Milaine Desaulniers’ full name is Raya Milaine Desaulniers. She teaches math. She played Animal Crossing with her sister during a pandemic. She walked one red carpet in 2019 and then went home. She hasn’t felt the need to explain herself. She doesn’t have to.
