BlackBerry has had quite the celebrity-filled week, launching Storm with John Mayer on Wednesday followed by its Bold launch party in LA on Thursday night. Kate Bosworth glowed in her simple and neutral-toned outfit, while Mario Lopez and Eva Longoria laughed and chatted together. Hayden Panettiere took a break from saving the whales to show off her new tattoo and posed with ex-boyfriend Stephen Colletti inside the party. Molly Sims and Rachel Zoe matched with their long wavy blond hair, and all of the stars looked like they had a blast on Halloween eve.
