Green Lantern stars Blake Lively and Ryan Reynolds presented a teaser trailer of their sure-to-be summer blockbuster at CinemaCon yesterday. "[My character] is not the classic damsel in distress," Lively (in Dolce & Gabbana) told CinemaBlend.com before making a wardrobe change to accept the award for Breakthrough Performer of the Year. "I was lucky to be able to play a great, strong character." Halfway around the world in Shanghai, Jessica Alba celebrated the opening of Diane von Furstenberg's new exhibition, while Michelle Monaghan continued her one-woman fashion tour with a stop in New York City for the premiere of Source Code.
