'Brie Larson' is her stage name.
It's a huge night for Brie Larson! She just won the Best Actress honor for her remarkable performance in Room and if you didn't already know about the incredibly talented star, here's what you should know:
The name on the star's birth certificate is actually Brianne Sidonie Desaulniers. It's French and the actress said she was sick of everyone butchering her last name even before she was famous, so she decided to change it. She claims she picked the surname Larson because she was obsessed with her American Girl doll Kirsten Larson as a kid. Boom.
