Jennifer Lopez Scares The 'Tight Pants' Off Jimmy Fallon

Jennifer Lopez just scared the pants off Jimmy Fallon.

Lopez stopped by "The Tonight Show" on Monday, June 9, to enjoy a little dancing in her tight pants, but when Fallon declares his pants are the tightest of them all, things go south quick.

"You better hide your wife! You better hide your kids! Because I will cut you!" says Lopez in a growl that could make anyone trade in their skinny jeans for a lifetime of sweatpants.

It's hard to blame Fallon for wanting to wear his groovy tight trousers, but when Lopez joins "The Tonight Show" in Orlando next week to promote her new album A.K.A., it'll probably be best to just go with a relaxed fit.

"The Tonight Show Starring Jimmy Fallon" airs weeknights at 11:35 p.m. ET on NBC.
