Phillip Phillips may have been named American Idol's new champ Wednesday, but prior to his coronation, all eyes were on judge Jennifer Lopez as she took the stage to perform "Goin' In" and "Follow the Leader."

Donning a longsleeve Blumarine dress with metal studs for most of the show, Lopez, 42, switched things up to rock the NOKIA Theater alongside her tour partners Wisin Y Yandel.

But rather than stick to her signature curve-hugging style, the mom of twins' on-stage look featured a white studded Versace bra and way-too-baggy sequined pants. The Bronx, N.Y.-born star accessorized her ensemble with a white New York Yankees baseball cap.

During the routine, Lopez showed off her toned arms and sexy abs as her backup dancers -- also clad entirely in white -- tumbled and performed other aerobatic tricks.

Topping Forbes' 2012 list of the most powerful celebrities, Lopez will not return for Idol's 12th season, a source confirms to Us Weekly. "There is just too much going on for her right now," the insider explains.

This summer, she'll hit the road with Enrique Iglesias for a 20-city U.S. and Latin American tour.
