Jennifer Lopez: Lap Dance in Las Vegas!

Jennifer Lopez wears a floral-print skirt on the set of her new movie, Parker, on Monday (September 26) in Boca Raton, Fla.

The 42-year-old entertainer got back to work on the crime thriller with co-star Jason Statham after spending the weekend in Las Vegas.

Jennifer performed at the iHeartRadio Music Festival before partying at Pure.

At the nightclub, one of Jen‘s backup dancers “took his shirt [off] and gave her a lap dance,” a source told People. “She was laughing and loving it.”

Jennifer also sang along to her hit song “On the Floor” and danced on the couch when the DJ played tracks by Rihanna and the Black Eyed Peas!
