And girl totally set FIAH to that stage!

We've been dishing about Jennifer Lopez's elusive American Idol performance for quite some time now, and last night Jenny SLAYED our expectations with a theatric, beautifully produced LIVE showing of her sensual hit song, Dance, Again.

We WILL dance, again J-Lo! Again, and again and again until you stop bringing such delectable a**-shaking treats to the table!

And is that Casper Smart we see, all naked and gyrating his hips all OVA Jen's body? HAH!

Get DOWN with Judge Jenny (above) and if you want more J-Lo love check out her summer tour with Enrique Iglesias!
