Justin Bieber was just one of the star guests at this year's amfAR event at the Cannes Film Festival.

Actress Sharon Stone presided over the auction for the Aids charity, which included one prize lot of a trip into space with Leonardo DiCaprio.

One star, who admitted she would not be bidding, was actress Jessica Chastain, who was put off last year by the spiralling auction prices.
