Pop diva Madonna reportedly performed a lap dance for a male model during a recent night out in Los Angeles.

Madonna, 51, was spotted getting cosy with model Adam Senn during the Moet & Chandon event for celebrity photographer Tom Munro on March 6, reports digitalspy.co.uk.

'She arrived with Adam from the back and sat in the VIP area. At one point, she got up and started dancing, and he was grabbing her waist and...,' said an insider.

'She turned around and gave him a lap dance and he looked like the happiest guy in the world,' the insider added.

However, a source added: 'She made sure no photos were taken.'
