This Should Help With Those "Party Boy" Rumors: NBC head Ben Silverman , who's never let running a network get in the way of being a party-positive "rock star," will be guesting on the upcoming fifth season of Entourage , says Nikki Finke . What kind of storyline might the HBO brofest have in store for Silverman? We imagine that after sparking up a doob with Vincent at Teddy's, a jealous Johnny Drama will grunt to Turtle, "I want to go hang out with that guy!" Their quest to befriend Silverman will result in a hilarious B-story that ends as all Entourage plotlines do: indifferently, punctuated by loud outbursts from Jeremy Piven. [Deadline Hollywood Daily ]
