Don't Miss:

Salma Hayek was in good company at the Il Mondo Vi Appartiene dinner at Fondazione Cini in Venice last night. The Gucci-clad actress, who was accompanied by husband Francois-Henri Pinault and daughter Valentina, rubbed elbows with guests like Monaco’s Charlotte Casiraghi (looking all grown up in Gucci). On the town in a different city were Emily Mortimer, Vera Farmiga, Heather Graham, Tiffani Theissen, Iman, who all hit summer soirees around the Big Apple.
