Jennifer Lopez is leaving it all "On the Floor!" The singer and actress, 55, put on a racy display with a trio of male dancers during her Friday, July 18, headline performance at the Cook Music Festival on the Spanish island of Tenerife. In clips circulating via social media, Lopez, clad in a silver bodysuit, can be seen on all fours gyrating onstage with one of her shirtless dancers, at one point seemingly going in for a kiss. The "Let's Get Loud" hitmaker is then joined by two more dancers, one whom she simulates backing up against while he is behind her.
