(Cover) - EN Showbiz - Jennifer Lopez enjoyed a sizzling lap dance after her performance this weekend.

The 42-year-old singer performed at the iHeartRadio music festival in Las Vegas on Saturday. Following the concert Jennifer immersed herself into the Vegas nightlife. She arrived with an entourage of more than a dozen people, including a bevy of backup dancers, to the VIP section of Pure Nightclub.

Jennifer sipped Dom Perignon champagne while watching her music videos playing on two massive screens at either side of the venue.

Around an hour into the festivities, Jennifer and gang decided to really let loose. One of her backup dancers pulled off his shirt and gave the star a memorable show.

"One of her dancers took his shirt and gave her a lap dance," a source told People magazine. "She was laughing and loving it."

Jennifer is currently undergoing a difficult divorce from estranged husband Marc Anthony, whom she has three-year-old twins with. The pair announced their separation in July of this year.

Although Jennifer's split from Marc is fresh, none of her personal struggles seemed to be on her mind at the discotheque.

Jennifer shook fans' hands, danced on the couch in her VIP area and left the club smiling around half past three in the morning.

Jennifer is currently a judge on American Idol, which will premiere in the US on January 22 2012. (C) Cover Media
