Jennifer Lopez took to the stage in Las Vegas Saturday night at the iHeartRadio music festival. She performed a medley of vintage hits along with new tracks like "Papi" and "On the Floor." Following the show Jen and her backup dancers moved the party to Pure nightclub where the entourage partied until 3:30 a.m. Things got wild in the VIP area of the club when one of J Lo's dancers stripped off his shirt and gave the singer a lap dance — which she reportedly loved. Jen's trip to Sin City reunited her with her fellow American Idol judges and host Ryan Seacrest, Steven Tyler, and Randy Jackson. Jen and the judges are in the midst of finding new talent for the show's eleventh season, airing in early 2012, in addition Jennifer's also currently filming Parker in Palm Beach, FL, alongside her sexy costar Jason Statham.
