urx unit loader Jennifer Lawrence recounts embarrassing J Lo moment, plays 'Box of Lies' on 'Tonight'

Actress Jennifer Lawrence stopped by “The Tonight Show” Thursday (May 15), where host Jimmy Fallon had her play a round of his on-going game “Box of Lies.” Hilarity ensued.

J-Law cracks jokes about her box and Fallon is so straight-faced when he’s basically telling the truth that Lawrence says, “If you’re not telling the truth, you’re basically a sociopath.”

Below, during J-Law’s interview, she explains about how she and Fallon conspired to dance with Jennifer Lopez after they had each done a bunch of jello shots, which … sounds like a great idea. But then Fallon abandoned the plan and left J-Law hanging as she asked J-Lo to dance all by herself

Lawrence also has a clip of her new movie, “X Men: Days of Future Past,” which is in theaters May 23. And it looks awesome.
