HBO definitely knows how to throw a party, and their annual bash to celebrate the Primetime Emmy Awards was no exception. Held in the courtyard at the Pacific Design Center in West Hollywood, guests partied in a huge tent with a theme meant to celebrate their recent 10-episode WWII epic The Pacific, winner of Outstanding Mini-Series. Autumn Reeser attended as well as her Entourage co-stars Jerry Ferrara and Perrey Reeves! To see pictures of Autumn at the event, view her new photo album here!
