She's never looked better!

Jennifer Lopez made an appearance on The Tonight Show on Monday and showed her comedic side by performing the skit "Tight Pants" with host Jimmy Fallon!

The singer was clad in white jeans and a crop top that showed off her unbelievably toned physique, but the fact that she was wearing a bowl cut wig made her slightly less attractive.

Jenny from the Block seems to be holding up fine since her split from Casper Smart!

"It has actually been an amicable process that started a few months ago. It wasn't an easy decision, but they decided to stay friends," a source told Us Weekly of the breakup.

We worship the ground J.Lo walks on!
