Amy Adams and Jason Segel jetted to Las Vegas to stir up buzz for The Muppets at the annual CinemaCon convention, where they treated the crowd to a sneak peek at scenes from their upcoming puppet flick. In New York, Diane Kruger arrived at the Runway to Green event wearing Jason Wu with Jason Wu. (Some girls have all the luck!) And back in Hollywood, Nicole Richie and Joel Madden took an outing to The Troubadour for the Vans X Jesse Jo launch party. See more photos from last night’s parties in the gallery.
