Meanwhile, Naomi Watts continued her well-documented love affair with Bulgari (she was spotted at three Toronto film fest events in Bulgari designs!): While celebrating her film St. Vincent, she selected a Serpenti necklace and Diva fan-motif earrings—proving the Deco trend is certainly here to stay.
