Watch: Jennifer Lopez Challenges Jimmy Fallon to Tight Pants Dance-Off

The two wore matching white pants and crop tops

It’s not often that a superstar argues with a late night comedian about whose pants are the tightest in town. But that’s what happened on Monday night, when Jennifer Lopez, 44, challenged Late Night host Jimmy Fallon, 39, to a dance off… in a pair of tight white pants.

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.”

This is not the first time that Fallon got into a dance-off, as the late night host got into a similar fight with Will Ferrell during a 2012 episode of Late Night.
