*Before the exit of Hollie Cavanagh from “American Idol” last night, judge Jennifer Lopez took the stage to perform her latest single “Dance Again,” and finished off the set doing a bump-and-grind with her background dancer/boyfriend Casper Smart.

During their PDA moment, which some blogs have labeled “cringe worthy,” Casper grabbed her derriere as they engaged in a steamy tango.

Then, as she and her dancers ended the number, Casper unfroze himself to take confetti out of J.Lo’s hair.

Just last year, J.Lo performed at the “Idol” finale with her estranged husband Marc Anthony. Was this performance intended to send a message to her ex?

Watch below, then scroll down to hear what Jennifer thought of her performance.
