Jenny’s walking down the block in tight pants! On Monday, June 9, Jennifer Lopez appeared on The Tonight Show, dancing in a crop top and white pants while singing the song “Tight Pants.”

In the tune, host Jimmy Fallon tried to claim that he, in fact, had the tightest pants, but even while wearing matching bowl cut wigs, it’s clear that Lopez, 44, and Fallon, 39, won’t be able to share the title of town’s tightest pants. Click here to see more pics of J.Lo through the years.

(Dancer-choreographer Smart, 27, meanwhile, slammed rumors of flings with transgender models Xristina Marie and Sofie Vissa. “There is no truth to any meeting or physical encounter,” he told Us Weekly.)
