Andy Cohen got Jennifer Lawrence to spill some interesting details about her personal life Monday night on "Watch What Happens Live!." In a lively game of Plead the Fifth, the star of "The Hunger Games" series admitted to kissing her co-star when the cameras were not rolling!

"It has recently been rumored that you and Liam Hemsworth had some PDA at the Waverly inn. Have you two ever kissed when the cameras weren't rolling?" Cohen asked Lawrence.

"Liam and I grew up together. Liam's real hot. What would you have done?...Yeah, I have," she admitted. "What would you have done?"

"I would say yes," Cohen said. "I mean, I pick Gale over Peeta any day."

"I did, at one point!" Lawrence said, getting a high five from Cohen.

In the second round of "Plead the Fifth," Cohen asked Lawrence if she had ever smoked marijuana before an awards show.

"I smoked pot at none of them, but I saw my brother smoking out of a bong at one of the Oscars. I won't say which," she said. When Cohen then pressed her if she had taken part, the Academy Award-winner cleared her throat before she muttered "Yeah."

"Was it when you won?" Cohen asked.

"I plead the fifth," Lawrence said.
