performed at the iHeartRadio Music Festival Saturday night, but she didn't end her night of dancing on the stage.
The singer hit up Las Vegas' Pure nightclub after her performance, and she and her friends reportedly kept the party going until 3:30 a.m. One of her backup dancers decided to heat things up even more, and stripped off his shirt to give the singer a lap dance in the VIP area -- which Lopez reportedly loved.
It was also an "American Idol" reunion of sorts earlier in the day, considering Lopez's fellow judges Steven Tyler and Randy Jackson were also at the music fest. "AI" host Ryan Seacrest was also on hand for the iHeartRadio festival weekend, which he helped put together with Clear Channel Radio.
But Lopez has a lot on her plate before she jumps back into her "Idol" duties. She recently released a new music video for her single, "Papi," and -- as if promoting her music career isn't hectic enough -- she's dealing with the fallout from her July split from husband Marc Anthony.
