Cameron Diaz looked stunning at the 82nd annual Academy Awards last night. Cam went for old school glamour, wearing a fabulous Oscar de la Renta ballgown which was embellished with gold sequins and metallic ribbons. The gown featured a full skirt and a form-fitting strapless bodice. Cameron accessorized with $50,000 Cartier white, yellow, rose gold and diamond pave "Trinity" hoop earrings and a Cartier white gold, princess and round cut diamond ring diamond, which retails for close to $60,000. Her hair was styled down in a classic side part, which is a big change for her. She looks elegant and beautiful.
