With the 'American Idol' contestants dwindling week by week, Casey Abrams is finding that it's getting 'Harder to Breathe.' Nevertheless, the favorite rocked the Maroon 5 single -- and even kissed J. Lo on the cheek.In a funny pre-performance segment, the six remaining contestants sported beards and called Abrams 'weird,' but the mop-headed hopeful showed them that he's got skills hiding in that facial hair.

Not only did he blow the roof off of the place with his full-band backed rock performance of Maroon 5's 'Harder to Breathe,' but Abrams took his showcase one step further and planted one on J. Lo, which surprised everyone.

"See, now Casey's not playing fair," a blushing Lopez said -- adding that the hopeful has soft lips. "You did what I've been trying to do for four months!" Steven Tyler told him.

"I loved it," J. Lo said, quickly correcting herself over the audience's laughter. "The performance! The performance! You brought all of your Casey-isms to it, you took a very pop-rock song and took it all the way rock. It was really great. Good job."

"What I love about Casey is it's about surprise, surprise, surprise," Randy Jackson contributed, adding that he was a bit worried beforehand. "I enjoyed it. You continue to take chances. It's almost as if you're a jazz, indie, kind of rock guy -- you fit all of those genres. I love the fact that you came down here and kissed her, we didn't even think that would happen."

"You already are a hero," the Aerosmith frontman said. "There's millions of people in America that are really angry, because you piss them off, because you're so f---ing good! You've changed so many people's minds because you're so good and you're that kind of an artist."

FOX may have bleeped out the rock n' roller for cursing during his compliments, but he's right -- Casey Abrams is so f---ing good! Watch out, America.
