Sharon Stone, Rosario Dawson and Paris Hilton were among some of Hollywood’s biggest stars who stunned at the De Grisogono "Fatale In Cannes" Party during the Cannes Film Festival on Tuesday.

56-year-old Stone looked radiant in a raspberry-colored Roberto Cavalli halter dress, which featured an embellished thigh-high slit. The "Basic Instinct" actress accessorized her gorgeous gown with an emerald and fuchsia De Grisogono necklace and matching dangling earrings. The blonde beauty brushed back her short tresses and completed her look with kohl-rimmed eyes and a pretty pink lip.

Amber Heard looked enchanting in an elegant Vionnet Spring 2014 look. The "3 Days to Kill” actress donned a white, cap-sleeved bodysuit and a gold high-waist maxi shirt, paired with a white Zaglilani clutch, nude Casadei pumps, and emerald-accented De Grisogono earrings. The blonde beauty styled her hair in a curly, shoulder-swooped style with a single side-braid. To complete her look, the future Mrs. Johnny Depp added a pop of color with a bright red lip.

Paris Hilton wowed in a black-and-white, long-sleeved, lace-embroidered Jean Fares Couture gown. The heiress accessorized her elegant ensemble with silver De Grisogono earrings, rings, and a matching watch. The blonde beauty styled her hair in a sleek up ‘do and topped off her lovely look by keeping her makeup looking radiant and natural. 

Rosie Huntington-Whiteley strut her stuff in a sexy, long-sleeved, black Cushnie Et Ochs dress with precision cutouts and a thigh-high slit. The supermodel paired this edgy outfit with De Grisogono diamond and emerald earrings and a diamond-studded necklace. The former Victoria’s Secret model wore her beautiful blonde locks in a straightened center-parted style and completed her look with winged eyeliner and a rose-colored lip.

Cara Delevingne stunned in a slate-grey Roberto Cavalli gown with intricate beading detail and a backless design. The 21 year-old model styled her elegant outfit with a single necklace, a large silver bangle, and several rings. To complete her look, the blonde bombshell wore her luscious locks in a chic chignon and sported her signature smoky eye makeup with a nude lip. 

Riley Keough sizzled in a shimmery, one-shouldered black Saint Laurent mini dress, which featured an asymmetrical hemline and a puffy sleeve. The "Runaways" actress complemented her dazzling dress with dangling silver and fuchsia De Grisogono earrings and white Stuart Weitzman sandals. The red-headed hottie topped off her look by keeping her makeup to minimum and styling her shoulder-length locks with loose curls.

And Rosario Dawson looked wonderful in a white floor-length Giorgio Armani gown with an embellished black neckline. The "Cesar Chavez" actress accessorized with a small black clutch, kept her makeup looking natural, and wore her brunette tresses in a wavy, side-swept style.
