Leave it up to J.Law to tell it like it is!

Jennifer Lawrence appeared on Watch What Happens Live last night, and admitted that she has kissed Hunger Games co-star Liam Hemsworth off-screen during a round of "Plead The Fifth" with host Andy Cohen.

The Bravo head honcho addressed the rumors that she was spotted snogging with the Aussie hunk at the Waverly Inn in NYC last month, and she basically had no choice but to roll with it. "Liam and I grew up together. Liam's real hot . . . What would you have done? I did [kiss Liam]. At one point," she blurted out.

Some of the Oscar winner's other revelations? She smoked pot before the Oscars and would never hook up with Justin Bieber if the opportunity presented itself!
