Jennifer Lopez glows!

Something must be in the water because two of the world’s biggest divas were off their game this evening on American Idol. Following Mariah Carey’s awkward hits medley performance, Jennifer Lopez hit the stage to debut her new single, “Live it Up”, but was strangely stiffer than usual.

Joined by Pitbull and his tight pants, Lopez strutted and twirled as she performed “Live it Up”. However, although she sang live over a backtrack, her moves were sluggish compared to her previous showings. Of course, Lopez still rocked the crowd and even earned a standing ovation from Carey, who has been her rival for years. “In your face” mission accomplished.
