Jennifer Lopez Falls Like A Champ At American Music Awards

J.Lo loses her footing after jumping in her 'Louboutins.'

It must be the shoes. After a few years out of the musical spotlight, [artist id="508574"]Jennifer Lopez[/artist] was clearly hoping to make a triumphant comeback on Sunday night at American Music Awards with a boxing-themed performance of her new homage to pricey shoes, "Louboutins."

Unfortunately for J. Lo, she lost her footing about halfway into the routine and briefly ended up on her famous derriere. Before Adam Lambert closed the show with a jaw-dropping routine that also included a slip that the musical theater vet deftly turned into a tuck and roll that almost felt choreographed, Jenny from the Block was not so lucky when she stumbled.

The fall came after Lopez walked up the backs of five of her dancers, who were arrayed like a set of steps. As jumped off the back of the top "step," her feet slid under her and she fell on her bottom. Always a pro, though, Lopez jumped right up and played it off as she segued into a solo dance spotlight, busting some moves as the phrase "The champ is here" played over the thumping beat.

Earlier, boxing announcer Michael Buffer gave Lopez the "Are you ready to rumble?" treatment as she was walked to the ring/stage by an entourage carrying a fake championship belt and flanked by male dancers in boxing shorts. Wearing a modified boxing robe with, Love?, the name of her upcoming album, on the back, Lopez lip-synched the mid-tempo dance tune. Near the end of the song, she pulled off an onstage costume change when her dancers helped her into a shiny gold mini-dress.
