The "I Luh Ya Papi" singer stopped by The Tonight Show, where she joined the TV host on stage. Both Lopez, 44, and Fallon, 39, wore a matching pair of tight white pants—much to the comic's dismay.
Before J.Lo appeared beside Fallon, however, the mop-topped jokester sang, "I'm the only one who's got my tight pants / I've got my tight pants / I've got my tight pants on / No one else around is wearing tight pants / I've got my tight pants / I've got my tight pants on." Lopez shimmied in his direction, inciting a mini-dance-off. Then the pop diva sang, "I can swing my arms / I can shake my hips / I can dance down the block knowing I'm the only chick that's wearing tight pants / and I'm the only one."
The two bickered over whose tight pants were the talk of the town, with the Bronx native growling, "Listen up, you little bitch. You better hide your wife, you better hide your kids, because I will cut you! I will cut your father, I will cut your mother, I will scratch you! Don't make me take off my hoops!"
After cooling down, Lopez told Fallon, "What I'm trying to say is get lost, applesauce. I'm the only one who can wear tight pants in this town. You feel me? Don't rattle the cage. We cool-o, papi chulo?"
In case you forgot, Fallon got into a similar fight with Will Ferrell during a 2012 episode of Late Night.
