‘On the Floor’ hitmaker Jennifer Lopez reminded all of how she gets down on the floor when she took tonight’s viewers of American Idol to task with her latest ‘Dance Again’.  ‘Again’, the first song lifted from Lopez’s forthcoming greatest hits collection, may not be performing as well on charts as some of the hits that will accompany it on the disc.

That, however, didn’t stop the mom-of-two from bringing the house down at tonight’s Idol showing.

See J. Lo lend a live rendition to her latest single below:
