If you thought you knew everything about Jennifer Lawrence, you might want to think again.

During her most recent appearance on Watch What Happens: Live, the actress acknowledged smoking pot before going to the Academy Awards and even confessed to kissing her Hunger Games co-star Liam Hemsworth off-camera.

Lawrence was given a round of “Plead the Fifth” since it was her first time appearing on WWHL. In this game, she was offered a “trio of impertinent questions,” but she could choose not to respond to one of them by pleading the fifth. The first query concerned Hemsworth and whether or not the two had ever made out off-camera.

“Liam and I grew up together. Liam’s real hot, what would you have done? Yeah,” Jennifer said when she was asked if she had ever kissed Liam off-screen.

“I would say ‘yes,’” said Cohen, with Lawrence responding in the affirmative. “I mean I’d pick Gale (Hemsworth) over Peeta (Josh Hutcherson) any day.”

“I did, at one point,” Lawrence laughed, before high-fiving the host. However, the actress was less forthcoming about her romantic life later in the show, refusing to comment on whether she was ever in a relationship with Coldplay frontman Chris Martin.

Cohen then asked if she’d ever “smoked pot before any award shows,” and Lawrence admitted to “taking a hit” off a bong before an Oscars ceremony.

She responded: “I’m actually the complete reserve. I smoked at none of them, but I saw my brother smoking out of a bong before one of the Oscars, won’t say which…”

However, the actress refused to say if it was during the year she had won the award.

She then did indeed plead the fifth for the third and final question at the suggestion of Cohen. It involved playing “Marry, shag, kill” with former co-stars Christian Bale, Bradley Cooper and Hutcherson. “Yeah, I plead the fifth because I don’t want to kill any of them,” she explained.

Cohen gushed about Lawrence after the interview, telling People magazine: “I love it when people are as enthusiastic about being here as we are about them being here, so it was perfect. I thought she was candid from top to bottom. I felt comfortable enough asking her about Chris Martin and everything else. I feel like she was a total open book, and I love it when guests come to play and when they’re willing to talk about anything.”

Lawrence’s new movie Joy opens in theaters on Christmas Day, while Watch What Happens Live returns on Jan. 3 with guests Bob Harper and Cynthia Bailey.
