The Joy actress played a game of Plead the Fifth with Watch What Happens Live host Andy Cohen consisting of three questions, one of them regarding whether a rumor she hooked up with Hemsworth was true.
"Liam and I grew up together," Lawrence, 25, said while shifting in her seat. "Liam's real hot. What would you have done?"
While admitting she had "at one point" kissed her co-star off-screen, Lawrence shut down reported advances by another famous heartthrob: Justin Bieber.
During the show, a caller relayed to Lawrence that Bieber thought she was "so sexy," and asked if she would ever consider a romantic rendezvous with the "Sorry" singer.
"I'm gonna say a hard no, but thanks," Lawrence said.
Speaking of romance, Lawrence last week confessed to a "delusional" crush on host Seth Meyers during an appearance on Late Night. "I had a really big crush on you, and so I had this whole plan," she told Meyers. "All week I was like, 'He's going to ask me out. He's totally going to ask me out.' Then later in the week I was like, 'I'm going to ask him out.' I had created the romance in my head because I'm delusional."
