Roberto Cavalli pulled out all the stops for his 40th anniversary bash last night. Held at the spectacular Les Beaux-Arts de Paris, a well-dress group of Hollywood progeny and fashions savants came out to toast the Italian Stallion, including Rachel Bilson, Heidi Klum, former FLARE cover girl Taylor Swift and Paris Vogue editrix Carine Roitfeld.
