Jennifer Lopez and David Cook hit the stage as musical guests on "American Idol" elimination night that aired May 10. The former showcased her new club track "Dance Again", while the latter debuted his fresh offering "The Last Song I'll Write for You".
Introduced by fellow "Idol" judges Randy Jackson and Steven Tyler, J.Lo heated up the show with her sexy and flirty performance. Wearing a cleavage-baring leotard, she stormed the stage with a handful of shirtless hunks including her dancer boyfriend Casper Smart.
Before J.Lo pumped up the crowd with her uplifting beat, Cook took the stage with his live band. Unlike the female judge, the 2008 "Idol" winner delivered a less crowded performance, but he still managed to get the crowd going with his rocking performance.
After the two performances, Ryan Seacrest announced the elimination. Hollie Cavanagh was sent packing, leaving Joshua Ledet, Jessica Sanchez and Phillip Phillips to go to the next round.
