Day 9 of the Cannes Film Festival saw A-listers dressing up in the name of charity for the AmfArRs Cinema Against AIDS benefit gala at the Hotel du Cap.

And it was a night of sophisticated designer dresses. Diane Kruger, Rachel Bilson and Kirsten Dunst went for glam in Chanel dresses while Michelle Williams went for short and daring in a sequined dress by Sonia Rykiel.

Fresh off her catwalk debut Mischa Barton went for Marchesa while Jennifer Lopez unsurprisingly opted for a pink princess frock by Roberto Cavalli.

Paris Hilton also turned up in a white bridal inspired number. However our best dressed starlets of the night have to be Kate Beckinsale, who looked amazing in a silver gown by Armani Prive and Emily Blunt who wowed us in a simple red dress.
