Brie Larson Opens Up About Her Reaction to Casey Affleck's Oscar Win & Her 'Bachelor' Obsession

The Oscar-winning star also shared a story about the reality star who made her so starstruck she hid at her own party.

Brie Larson
is opening up about her stoic reaction to Casey Affleck's win at the Oscars last month.

Speaking with Vanity Fair recently, the actress confirmed that her refusal to clap for the Manchester by the Sea actor had been correctly interpreted by the public.

The Room actress -- who is also an impassioned advocate for sexual assault survivors -- was tasked with presenting the Best Actor category at the star-studded awards show.

After announcing Affleck's name, Larson handed the golden statuette over to the actor, then stood at the back of the stage with her arms at her side as the audience gave him a round of applause. Some suggested that Larson's reaction to Affleck's win was a response to allegations of sexual harassment leveled against the actor, which had recently surfaced during awards season.

"I think that whatever it was that I did onstage kind of spoke for itself," Larson said at the Hollywood premiere of her new film Kong: Skull Island on Wednesday. "I've said all that I need to say about that topic."

In the months leading up to the Oscars, several articles dug up sexual harassment claims made by two women who worked with Affleck on the film I'm Still Here, which lead to a lawsuit against the actor in 2010. Affleck settled the suit out of court, and has subsequently denied the allegations.

While promoting her new action adventure epic on Thursday, the Oscar-winning actress sat down with Jimmy Kimmel, where she got a little more candid about a completely different topic that's played a large role in her life recently: her obsession with The Bachelor.

The 27-year-old star revealed that, despite being able to keep her wits about her while hanging out with some of Hollywood's biggest names, when this season's Bachelor, Nick Viall, showed up at her Bachelor viewing party, she got "freaked out and starstruck."

"I was too shy," said Larson, who's hosted a weekly Bachelor viewing party for quite some time. "The day before, I was like, hugging Meryl Streep and I was like, ‘This is fine,’ but then Nick showed up at my house."

"He stayed until the very end," she recounted. "He had such a good sense of humor about the whole thing, and I was just so nervous, I don’t think I said anything to him the whole time."

So, instead of striking up a conversation with the 36-year-old reality star, Larson said she spent the whole night surreptitiously snapping photos of Viall on her phone.

"I was just like, hiding, taking photos and sending them to Amy Schumer and being like, 'Uh, why did this happen? I’m too scared, I’m too shy,'" Larson joked.
