Jennifer Lopez rocks the runway and the beach in her new video for 'Live It Up' featuring Pitbull.

J to the L-O opens with primping backstage at a fashion show. She then models everything from a feathery, fashion-y black confection to a very tiny red bodysuit that shows off her infamous derriere. Then she dances her booty off and hits up the beach with Mr. Worldwide, where they spray champagne -- and where she sports a coverup that looks a lot like her infamous Versace Grammy dress, as well as a bikini and tangerine lips and nails. Dang, if we looked that good, we'd live it up too!
