Pop star MADONNA will serenade an auction winner with a private performance on her upcoming world tour - to raise $550,200 (GBP225,100) for an AIDS charity.
The lot was part of a Sharon Stone-hosted amfAR auction event at the Cannes Film Festival in France, and the lucky winner and a pal will be treated to an exclusive two-song show backstage on the legend's Sticky + Sweet roadtrip.
The Material Girl star - who was in Cannes promoting her AIDS documentary - appealed to the audience not to embarrass her with low offers when she introduced her lot.
She tells Gigwise.com, "People have offered me millions to platy at their Bar Mitzvahs."
