Madonna and P Diddy were amongst those auctioning off items at the annual Cinema Against AIDS gala in Cannes last week.
Madonna sold a private show for 350,000 Euros (£279,000). The two winning bidders, who remained anonymous, will be granted an audience with the singer backstage at a forthcoming concert, where she will sing two songs for them.
P Diddy offered the chance to spend 24 hours with him, which went for 200,000 Euros (£159,000). He promised to "wake up with" the winning bidder.
