Parties! The style, stars and scoop from Hollywood's hottest events

There was a mass celebrity exodus out of Cannes! Thankfully, it was just for a short trip down the coast for the annual hot ticket de Grisogono party at the Hotel du Cap's Eden Roc in Cap d’Antibes. Eva Mendes (in Versace), Beyoncé, Mischa Barton and other A-listers arrived at the luxurious resort by land and by sea, either stepping out of couture cars or disembarking from the massive yachts moored just outside to get the soirée started.
