Another tight pants face-off occurred on the latest episode of 'The Tonight Show Starring Jimmy Fallon.'

And this time, the television host was simply outclassed in every category.

Jennifer Lopez stopped by the late-night talk show on Monday (June 9th) to battle it out with Fallon over who had the tightest pants.

But as the 44 year-old showed off her toned midriff and famous derrière, there was only ever going to be one winner.

"I'm the only one in town with tight pants, I've got my tight pants, I've got my tight pants on, no one else around is wearing tight pants," Fallon says after coming from backstage, dressed in a pair of very tight white pants and a mop top wig.

In nearly exactly the same outfit, Lopez enters the stage and dances alongside Fallon, sending the studio audience into a frenzy.

"I'm the only chick that's wearing tight pants, and I'm the only one," J-Lo declares.

It didn't take long for the Brooklyn-born singer to get real tough as she got all in Fallon's face.

"Listen up, you little b---h. You better hide your wife, you better hide your kids, because I will cut you!" she shouted. "I will cut your father, I will cut your mother, I will scratch you. Don't make me take off my heels."

Lopez continued the ruthless rant and told the former 'SNL' star, "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 coolo, papi chulo?"

This may have been a rather fun distraction for the 'Dance Again' singer as she recently separated from her boyfriend of two and a half years, Casper Smart. They reportedly decided to call it quits after simply growing apart.
