AmfAR's annual Cinema Against AIDS event was held during the famous Cannes Film Festival at the Hotel du Cap in Antibes and featured a cocktail reception, dinner and a money-raising auction.
Movie mogul Harvey Weinstein and Heidi Klum started off the bidding by offering up a pricey Cartier watch and the supermodel sparked a bidding war by promising the winner a massage.
Weinstein told the crowd, ""If a man buys the watch, Heidi Klum will give that man a massage,"" before the piece sold for 50,000 Euros ($62,839/£39,274).
Other coveted lots in the auction included a guitar owned by Ronnie Wood and the chance to star in a short film by Karl Lagerfeld, while Vampire Diaries star Nina Dobrev offered to bite a winning bidder.
The night also included performances from Jessie J, who sang her money-themed hit Price Tag, and Aloe Blacc, who performed the aptly titled I Need a Dollar.
The event raised nearly $11 million (£8.9 million), according to The Hollywood Reporter. Other guests included Alec Baldwin, The Artist's Berenice Bejo, Milla Jovovich and Antonio Banderas.
