Naomi Watts wore some pretty — and pretty pricey — gems tonight as she hosted Bulgari's "Decades of Glamour" party in LA on Tuesday night. Naomi, who wore a vintage gold, amethyst, emerald, and diamond choker by the fine jeweler, jetted back to California for the bash after attending the brand's Fashion Week presentation in Milan over the weekend. The actress was Academy Award-nominated for her role in The Impossible last year and will be presenting at the 2014 Oscars on Sunday, but tonight was an opportunity for some more informal fun. We saw Naomi sharing some laughs with a miniskirt-clad Kate Hudson, who will also be on presenting duty this weekend, at the intimate rooftop bash.
Inside the exclusive soiree, attendees like Camilla Belle and Emmy Rossum mingled and admired some heavily guarded displays of some of Bulgari's most memorable red carpet pieces, including earrings and necklaces worn by stars like Sandra Bullock. The evening may have drawn its fair share of gem-loving starlets, but we also spotted a solo Jeremy Renner in the crowd, along with Catching Fire and Lone Survivor star Alexander Ludwig and his girlfriend. The party was one of just dozens being held in Hollywood this week as the countdown to Oscars Sunday ticks on; don't forget to cast your votes in our 2014 Oscars ballot for a chance to win $1,000!
