Who Is Milaine Desaulniers? Brie Larson’s Sister Has a Story Worth Telling

Everyone knows Brie Larson — the Oscar-winning actress who brought Captain Marvel to life. But not everyone knows her younger sister, Milaine Desaulniers, who has her own inspiring story to tell.

While Brie grew up to become one of Hollywood’s most loved stars, Milaine chose a much quieter and simpler life. She stayed out of fame but never far from heart. Her story is full of warmth, family love, and silent strength — proof that not every hero wears a cape or walks a red carpet.

In this article, we’ll look at who Milaine Desaulniers really is — her early life, her bond with Brie, their family’s struggles, and how she built a peaceful life of her own.

Milaine Desaulniers Quick Bio

Growing Up with Brie Larson

Milaine Desaulniers grew up in Sacramento, California, alongside her older sister, Brie Larson (born Brianne Sidonie Desaulniers). Their early years were filled with laughter, creativity, and small family moments that shaped who they would become.

The sisters were close from the start. Brie was full of imagination and big dreams, while Milaine was gentle and curious. Together, they spent hours making up stories and little games, often turning simple moments into fun adventures.

Before Hollywood fame came into their lives, they were just two sisters who loved each other deeply — two little girls who had no idea how much their lives would soon change.

Meet Her Parents: Heather and Sylvain Desaulniers

Milaine’s parents, Heather and Sylvain Desaulniers, were both chiropractors who believed in natural healing and homeopathic care. They worked together at their own practice in Sacramento and built a quiet, healthy family life.

Their father, Sylvain, is French Canadian, which is why Brie’s real last name is Desaulniers — a name that shows their French roots. Brie even spoke French as her first language when she was little, though she later forgot most of it.

Their mother, Heather, was always creative and caring. She understood her daughters’ dreams and wanted to give them every chance to grow. Even though life wasn’t always easy, she gave her girls a warm and loving home filled with encouragement and love.

Life Changed After the Divorce

When Milaine Desaulniers was only two years old, her parents’ marriage came to an end. Brie was seven at the time. The divorce changed everything for the family and marked the start of a new, more difficult chapter.

Heather became a single mom, raising both girls on her own. She wanted to give Brie a chance to chase her acting dreams, so she decided to move the family from Sacramento to Los Angeles. At first, the trip was meant to last only a few weeks. But it soon became their new life.

This was a tough time — not just financially, but emotionally too. The sisters missed the feeling of having a complete family. But Heather stayed strong and made sure her daughters felt loved and safe, no matter how small their home was.

A One-Room Life in Los Angeles

When they first arrived in Los Angeles, Heather rented a tiny studio apartment. It had a fold-out bed that came out of the wall — and that single bed was shared by Heather, Brie, and Milaine.

Money was tight. Most nights, they ate ramen noodles or 99¢ tacos. Yet, somehow, Heather made it feel like an adventure. She decorated the small space, played games with her daughters, and turned each day into a story.

Brie later said in interviews that she never saw that time as sad. She remembered it as warm and magical — a time when love made up for everything they didn’t have. And little Milaine, just a toddler, grew up surrounded by that same love and laughter.

A Sisterly Bond That Stayed Strong

Through every hard moment, Milaine Desaulniers and Brie Larson leaned on each other. They were not just sisters — they were best friends.

While Brie began auditioning for acting roles, Milaine often tagged along, learning to stay patient and cheerful. They played together, laughed together, and sometimes cried together too.

As they grew older, life took them in different directions — Brie to Hollywood, Milaine to a more private life — but their bond never faded. They stayed close, always supporting one another through distance, fame, and time.

Playing Games, Making Memories

One of the sweetest parts of Milaine Desaulniers’ childhood was her love of video games. Both she and Brie were obsessed with Animal Crossing on the Nintendo GameCube.

Their mom even used it as a fun way to get them to finish homework — promising game time as a reward. For the sisters, the game was more than entertainment; it was their safe world, a little escape from real life.

Years later, during the COVID-19 pandemic, they reconnected through the same game again — this time playing Animal Crossing: New Horizons from their homes. It reminded them of their younger days and brought back happy memories of childhood comfort.

What Does Milaine Desaulniers Do Today?

While her sister Brie is busy walking red carpets, Milaine Desaulniers lives a quiet and calm life. She is not part of Hollywood and doesn’t appear in the spotlight often.

Milaine works as a mathematics teacher. She enjoys helping others learn, and her job is far from the cameras and crowds. Teaching allows her to use her mind, stay grounded, and live a peaceful life.

She has kept most details of her daily life private. But one thing is clear — Milaine is happy building her own path, and she doesn’t need fame to feel fulfilled.

Has Milaine Ever Been in Films?

Even though she didn’t become a Hollywood star like Brie, Milaine Desaulniers has been linked to a few creative projects. These include:

• The Arm (2012)

• The Dew Project (2021)

• Warning: Childhood Cringe (2021)

These projects seem small, possibly student or short films. It’s unclear whether Milaine acted, helped behind the scenes, or was simply credited in another way. Still, this shows she has a creative side too.

Though her main focus is teaching, these projects remind us that creativity runs in the family.

A Complicated Relationship with Their Dad

Family relationships are never simple — and for Milaine Desaulniers and Brie Larson, things were especially hard with their father, Sylvain.

Brie has shared in interviews that she hasn’t spoken to her dad in many years. She said he didn’t really want to be a parent and that she stopped visits once she was legally allowed to.

Milaine has never spoken publicly about her own relationship with him, but it seems likely that she also kept her distance. After the divorce, Sylvain stayed in Sacramento while the girls grew up in Los Angeles.

Despite the distance, Sylvain once said in an interview that he loves his daughters and is proud of Brie. He still keeps old photos of them and said he watched Brie’s movie Room three times.

Public Moments and Rare Appearances

Milaine Desaulniers keeps her life out of the public eye, but she has made a few rare appearances to support her sister.

One sweet moment was at the 91st Annual Academy Awards in 2019, when Milaine attended the event with Brie. Dressed beautifully, she stood by her sister on one of the biggest nights in Hollywood.

Even before that, their mother Heather had joined Brie on stage during her Saturday Night Live monologue — showing how close and supportive the family remains.

Milaine may not be famous, but her love and support are always present behind the scenes.

Milaine Desaulniers in 2025: Where Is She Now?

As of 2025, Milaine Desaulniers continues to live a very private and peaceful life. She’s not on social media, and she avoids the spotlight completely.

She is still believed to be teaching and spending time with her close family. Milaine’s connection with Brie remains strong, even though they lead very different lives.

She doesn’t chase fame, and that’s what makes her story so beautiful. Milaine is proof that a quiet life can still be rich with meaning, love, and success.

Final Thoughts

Some people shine in the spotlight, while others shine in the background. Milaine Desaulniers may not be a Hollywood star, but her life is full of quiet strength and real love.

From sharing a tiny bed with her mom and sister to becoming a kind teacher, she has always walked her own path. She’s the kind of person who stays strong in hard times and supports those she loves — even when no one’s watching.

Her story reminds us that not all heroes are famous. Sometimes, the most powerful stories belong to the ones who live with heart, courage, and quiet grace.
