Jennifer Lopez made three costume changes yesterday on the set of Parker in Palm Beach, FL. She was joined by her sexy costar Jason Statham, who's a big fan of Jen's daughter Emme. Jason reportedly struck up a quick friendship with 3-year-old Emme when she visited Jen at work. Emme and Max often travel with Jen, and they might be up for a trip to Las Vegas this weekend. Jennifer is among the many artists taking part in the iHeartRadio music festival. She's scheduled to take the stage tomorrow night and will likely perform a mix of her old hits and new tracks from the LOVE? album, including her latest single "Papi."
