VIDEO: Jennifer Lawrence plays 'Box of Lies' on 'Tonight Show'

Jennifer Lawrence played 'Box of Lies' on The Tonight Show starring Jimmy Fallon.

Rules: Jennifer and Jimmy pick items from a box and describe it. They will then try to figure out if the other is lying.

I love Jennifer so much! Can she lie her way to a win?

She's so game for anything. Love her hair.

Her movie X-Men: Days of Future Past comes out on May 23, 2014.
