Pop star Jennifer Lopez swapped the judging panel for the stage tonight when she performed on ‘American Idol‘.

Lopez, 41, wowed with an electrifying debut performance of her global smash ‘On The Floor’. It’s hoped the high-profile slot will give a much needed boast to the singer’s ‘LOVE?’ LP; which looks set to arrive on the Billboard 200 with disappointing figures.

Lights, lazers, and a mid-drift baring diva await after the jump…
