Sharon Stone, 63, was beaming with joy as she posed for photos with her oldest child Roan Bronstein Stone, 21, at the Cannes Film Festival! The Basic Instinct icon brought her rarely seen son to the star-studded 27th annual amfAR Gala on July 16, which was held during the Cannes Film Festival to raise funds and awareness for HIV/AIDS. Sharon looked absolutely stunning in a lavender colored gown that was adorned with crystal details around the bodice area.
