Brie Larson took a moment to thank her longtime boyfriend Alex Greenwald while accepting her Oscar Sunday night.

Brie Larson Thanks Alex Greenwald

Larson picked up the Best Actress in a Leading Role Academy Award for her performance in Room as a mother who is forced to raise her young son in a small room, which he is led to believe is the entire world. Upon accepting the trophy, Larson thanked the 9-year-old actor who played her son, Jacob Tremblay, and then singled out Greenwald.

“Thank you first to the Academy. I want to start big because the thing I love about movie making is how many people it takes to make it,” Larson said. After thanking film festivals that gave the movie a platform and the crew, Larson continued, “Jacob Tremblay, my partner through this in every way possible – my real partner, Alex Greenwald, I love you, the whole thing.”

Larson has been dating Greenwald, who was previously a part of the band Phantom Planet, for a few years. Though Larson is generally tightlipped when it comes to answering questions about her musician/producer partner, she has gushed about him being her best friend.

“He’s the other half of the equation — how can you explain support?” she told Entertainment Tonight earlier this year about Greenwald “I mean, it goes beyond anything. He’s just my person, he’s my best friend.”

Prior to collecting the Best Actress in a Leading Role Oscar, Larson won in the category at the Golden Globes, SAG Awards and BAFTAs.
