Sharon Stone

(in Dior) didn't disappoint the guests at the Cinema Against AIDS gala who were looking to score some one of a kind auction items. Among the luxury goods on the block- President Bill Clinton’s autographed Alpine Alto Saxophone, a custom "personal transporter" from fashiion house Chanel and a diamond-studded a Chopard watch co-designed by Sir Elton John. To up the ante, Stone even offered up a kiss on the cheek from Twilight hearthrob Robert Pattinson (in Dolce amp Gabbana), which sold for $20,000.

Hayden Panettiere's Cinema Against AIDS dress covered both the long and the short of the fashion spectrum-the actress chose a blush silk-chiffon Marchesa dress with a delicate train for the affair, held at the super-luxe Hotel du Cap in Antibes.

Glamorous couple Joshua Jackson and Diane Kruger (in Marchesa) attended the after-party for Quentin Tarantino's new film, Inglourious Basterds, starring Brad Pitt, at Baoli Beach in Cannes.

Brad Pitt and Angelina Jolie were the center of the Cannes universe when they walked the red carpet at the premiere of Inglourious Bastards. While Pitt was dapper in a Tom Ford tux, Jolie accented her delicate Versace chiffon gown with racy red lips.

Before jetting off to Italy to join his co-stars on the European set of New Moon, Robert Pattinson took a quick trip down the red carpet at the Palais des Festivals before heading inside to catch the screening of Inglourious Basterds.

Earlier in the day, Pitt joined his on screen leading lady, Diane Kruger (in a vintage strapless dress and fine jewelry by Chanel), at a photocall for the Quentin Tarantino flick. Asked about his Riviera style by the Today show's Anne Curry, Pitt revealed that he had been "personally dressed," by designer Tom Ford for the occasion.

Twilight series star Robert Pattinson took a break from filming New Moon to jet to the French Riviera, where he stirred up buzz for the sequel-and showed off his trademark tresses-during a photo call at the Magestic Pier.

Penelope Cruz recovered from a bout of food poisoning just in time to help host the Hollywood Domino Tournament, which raised funds for her favorite charity, The Global Fund inspired by (RED). Despite feeling under the weather, Cruz looked picture perfect in a John Richmond dress and Balmain tuxedo jacket-adding extra sparkle with a Roger Vivier clutch-when she arrived at the Akvinta-sponsored event, held at a private villa.

Hilary Swank

made a dramatic entrance at the premiere of Looking for Eric, going geometric in an Armani Prive metallic organza gown with edgy details like a cascading, multi-tiered train and Sergio Rossi shoes.

Like Weisz, Evangeline Lilly also chose Valentino for her first red carpet walk at Cannes. The Lost star looked elegant in an embroidered lace gown at the premiere of Vengeance.

Malin Ackerman channeled old school glamour in head to toe Prada when she joined co-star Ryan Phillippe for a cocktail reception to promote their movie, The Bang Bang Club at the La Plage du Petit Club. "I have a friend who works at Prada," Ackerman explained when asked about her look. "I'm very lucky!"

Abbie Cornish chose a lilac gown by designer-and fellow Australian-Toni Maticevski for the premiere of Bright Star at the Palais Des Festivals. "I'm leaving in a couple of days but, since [the movie] is in competition, I may come back for the Palme d'Or presentation," said the actress, who hit spent her time in Cannes with boyfriend Ryan Phillippe.

Eva Longoria Parker made her first red carpet appearance at the 2009 festival a memorable one, donning a silk organza embroidered ball gown by Versace Atelier for the premiere of Bright Star at the Palais des Festivals.

Banks, who is attending the festival as a spokesperson for beauty brand L'Oreal, made her first red carpet appearance in a a Giorgio Armani Privé one-shoulder silk evening gown and Chopard jewels.

Festival juror Robin Wright Penn dazzled in a platinum draped gown by Elie Saab Vintage Couture and diamonds from the Louis Vuitton Les Ardentes jewelry collection at the premiere of Up.
