Jennifer Lopez hasn't debuted new music in quite some time, but the wait is over! The American Idol judge has released her new single, On The Floor.

AI host Ryan Seacrest gave the new dance song a whirl on KIIS-FM this morning. The heavily synthesized track, also featuring Miami rapper Pitbull, was produced by Red one ... who worked with Lady Gaga on Bad Romance and Poker Face.

With Idol's 10th season premiering tomorrow, the timing couldn't be more perfect!
