*Jennifer Lopez used her “American Idol” co-worker Ryan Seacrest to debut a new single this morning.

The day before she debuts as an “American Idol” judge, the singer/actress/entrepreneur unveiled her new single “On the Floor” on Seacrest’s LA-based radio show On Air with Ryan Seacrest.

Produced by RedOne, Lopez sings over a techno beat, which incorporates a sample of Kaoma’s worldwide hit “Lambada.”

“If you go hard, you gotta get on the floor/ If you’re a party freak, then step on the floor/ If you’re an animal, then tear up the floor/ Break a sweat on the floor/ Yeah, we work on the floor,” she sings.

The track features assistance from rapper Pitbull.

J. Lo has been teasing fans about her collaboration with super-producer RedOne (Lady Gaga’s “Just Dance” and “Bad Romance”) via Twitter. “I see u @RedOne_Official! We’re making BIG things happen ‘On the Floor’ this new year!!!” she wrote last week.
