The 23-year-old actress was dancing with 'Tonight Show' host Jimmy Fallon at a recent charity party when they spotted the 'I Luh Ya Papi' hitmaker and decided to ask her to join in, reported Ace Showbiz.
"We came up with this plan together. We're dancing, we see JLo and we're like, 'We've got to ask JLo to dance!' And I was like, we'll do a spin and then we'll go, 'Dance with us'. Basically, I do it, and then I look and he's (Jimmy) gone!," Lawrence said.
