WATCH: Jennifer Lawrence, Jimmy Fallon and John Oliver Play ‘True Confessions’ 

Did JLaw just admit to taking an Ambien before filming a scene in the Hunger Games series?

Jennifer Lawrence sat down with The Tonight Show’s Jimmy Fallon and Last Week Tonight’s John Oliver for a game of “True Confessions” involving Tokyo saunas, boogers and the Queen of England.

Here’s how it works: Each of the three participants is given two envelopes, one containing a confession and one containing a bold-faced lie. The other two choose the envelope to be read and then interrogate the confessor to learn if they are telling the truth or elaborating upon a ridiculous fib. This game is all about the poker face, or lack thereof.

The Joy actress went first, reading, “I took an Ambien before filming a scene in The Hunger Games.” In no time, this trio drummed up lots of reasons an actress would pop a sleeping pill before filming a scene in an action film, some more logical than others.

Fallon’s “confession,” which involves a member of the Beatles, is so bizarre and sweet, it simply has to be true.
