Madonna may be 51, but she still can give a good lap dance! The icon showed up to the Moët & Chandon celebrity photographer Tom Munro private viewing in LA on March 6 with a new younger man, The City star and Dolce & Gabbana model, Adam Senn. “She arrived with Adam from the back and sat in the VIP area,” an onlooker tells In Touch. “At one point, she got up and started dancing, and he was grabbing her waist and touching her butt. She turned around and gave him a lap dance and he looked like the happiest guy in the world.” But Madge was keen on keeping her new beau under wraps. “She made sure no photos were taken.”
