Leonardo DiCaprio has auctioned off a trip to space which he will accompany the winner on for 700,000 euros.
The Wolf Of Wall Street star raised the money - more than half a million pounds - at a charity auction for amfAR, which funds Aids research, at the Hotel du Cap-Eden-Roc outside of Cannes.
Leo sold off the space trip for 2015, contributing to the night's overall fundraising of £22.5 million. He also offered the prize at last year's auction.
Other auction items included a 1967 Andy Warhol painting of Marilyn Monroe, a 1968 Picasso and a piece of art by Damien Hirst.
Joining Leo at the event were amfAR chairs Sharon Stone, Harvey Weinstein, Milla Jovovich, Heidi Klum and John Travolta, as well as guests Jane Fonda, Jessica Chastain, Kylie Minogue, Marion Cotillard, Rosario Dawson, Justin Bieber, Michelle Rodriguez, Kellan Lutz and Paris Hilton.
Host Sharon said: "Today is the day we can say we have a cure for paediatric Aids... Now we are in the beginning of the end of Aids."
She added: "I'm exhausted. I've been doing this for 20 years."
They enjoyed performances from Lana Del Rey, Robin Thicke, and Andrea Boticelli who sang My Way in tribute to Elizabeth Taylor, who founded amfAR in 1993.
