Emmy Rossum: Ali Larter's Cookbook Celebration!

Emmy Rossum steps out in style at a party for Ali Larter‘s new cookbook “Kitchen Revelry” with Perrier-Jouet held at Sunset Tower on Tuesday (August 27) in West Hollywood, Calif.

The 26-year-old actress was joined at the event by Jamie Chung, Rain Phoenix, and Ali herself!

“Tuesday night, playing on this matchmaking app called #hookwink that matches up your friends on #Facebook.” Emmy tweeted that evening. Sounds fun!

“Guestlist is closed! Party exploded! I can’t wait to celebrate my book #kitchenrevelry with my besties tonight!” Ali tweeted that evening.

FYI: Emmy is wearing a Moschino jumper and Red Valentino skirt from my-wardrobe.com. She is carrying a Rebecca Minkoff clutch. Jamie is wearing an Ann Taylor skirt. Ali is wearing Marchesa.
