Blake Lively stepped out in a white Dolce & Gabbana number at CinemaCon in Las Vegas this afternoon. She's in Sin City to accept the award for breakthrough performer of the year after heading to the West Coast to film an episode of Gossip Girl last week. Blake's closing out the convention with her appearance, though there have been plenty of celebrities in the spotlight during the four-day event. Emma Stone and Bryce Dallas Howard popped up to promote The Help, which is just one of many book adaptations to hit the big screen this year. Amy Adams and Jason Segel were also on hand for their upcoming project, The Muppets, while Cameron Diaz showed off her Summer comedy, Bad Teacher. Cameron also took home the Female Star of the Year Award and shared a sweet moment on stage with pal and presenter Drew Barrymore.
