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]
