Latin pop's finest -- Jennifer Lopez and Pitbull -- return with the video for their bottle-popping track "Live It Up." Jenny From the Block crawls on all fours on the catwalk and swings through the air flaunting her new slimmed-down body in the Jessy Terrero-directed video. The duo performed the club banger earlier in the week on the American Idol season finale. See if you can spot a pseudo cameo from J. Lo's plunging green 2000 Versace dress in the video.
