Saturday's Environmental Media Awards in Burbank, California may have unwittingly contributed to global warming thanks to Hollywood's hottest (and greenest!) stars, who came out in droves for the event. Jessica Alba (in Narciso Rodriguez) suited up for the event with Amy Smart, while mom-to-be Malin Akerman posed cheek-to-cheek with Revenge star Emily VanCamp (in Andrew Gn). Also at the fashionable affair: Emmy-winner Julie Bowen, who caught up with Carla Gugino. Click through to see Scarlett Johansson, Eva Longoria and more stars at this week's hottest events.
