Oscar-winner Jennifer Lawrence stopped by The Tonight Show Thursday night to promote X-Me: Days of Future Past and had some fun with the host while she was there.

These two have great chemistry, and Jennifer Lawrence looks like she’d be a blast to hang out with. During the segment, Jimmy Fallon challenged the lively actress to a game of “Box of Lies.”

Taking turns, each person had to pick special boxes and then either tell the truth or fib about its contents, such as a sticky Rubik’s Cube in a bowl of jell-o).

Watch as these two try to fake each other out, but can’t stop laughing.

Also while there, Lawrence called out Fallon for leaving her in a funny predicament on the dance floor in front of Jennifer Lopez at a recent charity event.

“You came up with this idea. We’ll do a spin and then she will dance with us,” Lawrence revealed, admitting that she was more than a few jell-o shots down. “I do it then I look at him and he’s gone and she’s just looking at me. You made me look like a freak in front of J-Lo.”
