Is Jennifer Lawrence Watching? Fallon Dances with JLo!

On Tuesday's Tonight Show, Jimmy Fallon got a little closer to making a "J.Lo, J.Law, J.Fall" dance party! "Jennifer Lawrence, I hope you're watching!"

Recalling the time the 23-year-old Hunger Games actress put the 39-year-old host on blast for bailing on her when they agreed to ask Jennifer Lopez to dance with them at the Met Gala, Fallon came through on his word and busted a few moves with the 44-year-old American Idol judge.

J.Lo explained why she denied J.Law a dance, saying it was a "mosh pit" on the dance floor once Kanye West started performing. "I didn't mean it like that. I just mean it is crazy out there," she said.

She also sided with Lawrence for being mad at Fallon, and even called him out for "bailing on the bit." Would you like to see this trio dance?
