Dolores Chaplin (in the photo above) wore a Serpenti watch in yellow gold and diamonds, Serpenti pink gold earrings, and a Serpenti clutch.
Other celebrities at Cannes who wore Bulgari included Josephine de la Baume (below), who was at the premiere for Confession of a Child of the Century, wearing an HJ Ring in platinum and emerald-cut diamond, baguette rubies, and diamonds pave.
Orson Salazar and Paz Vega (below) were wearing Bulgari sunglasses at Nice airport.
