Sharon Stone left little to the imagination this week at the annual amfAR gala in the south of France.
The sexy 56-year-old went backless in a red Cavalli dress with circle cutouts around her waist (actually around below her waist).
The gala, which is held annually in Cap d'Antibes, France, which is a quick 20-minute drive down the Riviera from Cannes.
Each year the event is attended by the biggest names in showbiz and modeling, and this year was no exception.
Supermodels Heidi Klum, Irina Shayk and Alessandra Ambrosio were all on hand for the event, along with Nicole Scherzinger, Jessica Chastain and even The Biebs, who wore the sleeves of his tux rolled off to show off all of his ink.
This year's gala raised a staggering $38 million -- up 50 percent from last year's total -- for AIDS research.
