You’ll find her under three names online. Records list Raya Milaine Desaulniers, Milaine Desaulniers, and Mimsy Desaulniers. They point to the same person. That’s why search results can feel messy.
Milaine Desaulniers Age and Birthday
Public sources report that Milaine Desaulniers was born on January 5, 1993. That makes her 33 years old in 2026. Brie was born in October 1989. So the two sisters sit about three years apart. Milaine turned 33 early this year, and she didn’t make a big public show of it.
Here’s a fair warning. The birthday comes from public biographical records. It hasn’t come from a formal interview. So it’s smart to call it the “reported” date. That small habit keeps your facts honest. It also builds trust with readers who double-check everything.
Milaine Desaulniers’ Parents and Family Background
Milaine’s parents are Heather Desaulniers and Sylvain Desaulniers. Both worked in holistic health. Reports describe them as homeopathic chiropractors who ran a joint practice in Sacramento. Their home put natural healing and wellness first. Think herbal teas over cough syrup. That upbringing shaped how both girls grew up.
Family sat at the center of everything. The sisters spent their earliest years in a close-knit home. Then life shifted fast. Those changes made the bond between Milaine and Brie stronger. You’ll see how in the next sections.
Heather and Sylvain Desaulniers
Heather grew up in California. She became the steady anchor after the family split. Sylvain has been described as a chiropractor with French-Canadian roots. Brie has spoken openly about her tough relationship with him. Milaine hasn’t joined those public talks, and that choice deserves respect.
French-Canadian Roots
The Desaulniers surname traces back to Sylvain’s Franco-Manitoban family. French was even Brie’s first language in early childhood. She later lost most of it. The heritage still lives in the family name.
Early Life: From Sacramento to Los Angeles
Milaine Desaulniers started life in Sacramento, California. It was a calm place with a warm home. Then her parents divorced when Milaine was a toddler. Heather packed up and moved the girls to Los Angeles. The plan was a short trip for Brie’s acting chances. The trip turned permanent. Imagine leaving for a three-week visit and never going back.
Money stayed tight in those years. Heather raised two daughters alone. Still, she kept the mood bright. Brie later called that time “one of the greatest times in my life.” That says a lot about a mother who turned scarcity into play.
Life After the Divorce
After the split, Heather became a single parent juggling bills and auditions. Milaine was too young to understand it all. Brie was seven and felt the weight more. The divorce left Brie with a rocky bond with her father. Later, she stopped visiting him once she was legally free to do so.
The Studio Apartment Years
The family settled in a one-room studio apartment at the Oakwood Apartments in Burbank. A Murphy bed folded out of the wall, and all three slept on it. Meals came from instant ramen and cheap fast-food tacos. Brie’s later film Room echoes that theme of a mother shielding her child through imagination. The details are small, but they paint a vivid picture.
Milaine Desaulniers and Brie Larson: The Sisterly Bond
The bond between Milaine Desaulniers and Brie Larson survived fame, moves, and money stress. They grew up sharing a tiny space and big dreams. Milaine stayed in the background and Brie stepped into the spotlight. Yet neither sister drifted away. Milaine acts like a grounding influence. She reminds Brie of life outside Hollywood’s bubble. Few things keep a star humble like a sister who knew her before the red carpet.
Their shared father story also drew them closer. Both sisters have a distant relationship with him. That common ground adds another layer to their closeness. Today they still travel together with their mother from time to time. It’s a simple, warm picture of family.
Their Shared Love for Animal Crossing
Video games gave the sisters a happy escape. Their Nintendo GameCube held Animal Crossing, and it became a childhood favorite. Heather even made a rule that homework came first. Years later, Animal Crossing: New Horizons arrived during the pandemic. The sisters visited each other’s islands and chatted over FaceTime. Brie called it “sweet” that two adults still loved the same game.
The 2019 Oscars Appearance
Milaine’s most famous public moment came at the 91st Academy Awards on February 24, 2019. She walked the red carpet beside Brie at the Dolby Theatre. Photographers caught the pair holding hands. It was a rare peek at their closeness. Milaine didn’t turn it into a media career, and she went right back to her private life.

Education and Teaching Record
Some professional profiles link her to the University of California, Irvine. Treat that as supporting info rather than a confirmed fact. Profiles are often self-reported. A full list of her degrees isn’t public. So it’s wiser to share only what sources can back up.
Case study: the Valentine’s Day hearts. A 2020 local report linked Mimsy Desaulniers to an ASB project at Valencia High School.
