Creator Doug Ellin told Entertainment Weekly that Eminem won't be performing in the season ender, but will have a conflict with Vince (Adrian Grenier) — not surprising since the rapper has been known to poke fun at entertainers (Jessica Simpson, Lindsay LohanGov. Sarah Palin, to name a few). 

Eminem's latest album Recovery was released June 18; in the HBO series, he'll be in a scene taking place at his album's platinum record party. Ellin says he's confident that Recovery will indeed be platinum by the time the episode airs (Sept. 12).
