We spotted the boys of Entourage are hard at work in West Hollywood yesterday.  Now entering its fifth season, the new episodes should premiere on HBO sometime this fall, it had originally planned to air earlier but had been pushed back due to that old chestnut we fondly refer to as the "writer’s strike."  Returning to form, the show will have it’s share of celebrity cameos, Hollywood.Tv caught a scene between E (Kevin Connolly) and Bow Wow.  I would personally know when producer Mark Wahlberg is showing up in a scene…shirtless.
