Watch The Lonely Island Pick Their Celebrity Entourage

The Lonely Island's Popstar: Never Stop Never Stopping comes out this Friday, and the crew did a pretty fine job of selecting the cast. Of course, Andy Samberg, Jorma Taccone and Akiva Schaffer play the main characters (Samberg being the pop star mentioned), but they also gathered together Hollywood's funniest, including Bill Hader, Maya Rudolph, Will Arnett, Sarah Silverman and Will Forte.
