Jennifer Lopez appeared on The Tonight Show Starring Jimmy Fallon on Monday night, where the two had a tight pants dance off.

Complete with bad wigs, tight white pants and bad ‘60s shoes, Lopez and Fallon sang and danced about being the king and queen of wearing tight pants.

People reports Lopez told Fallon the mayor presented her with a plaque that declared she had the tightest pants “in all the land,” but Fallon replies he got a “telegram” from the governor declaring “Tight Pants Day” in honor of his pants.

She then shot back, "I'm the only one who can wear tight pants in this town,” adding, "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 heels."

Lopez took to Twitter to show off her tight pants, writing, “Made it to #FallonTonight with my #TightPants!! @JimmyFallon #JLoAKA #JLoJune17.”
