Entourage

Coming off a lackluster premiere, Entourage has some exciting news for fans: both Eminem and Christina Aguilera will play themselves on this season's finale.

First, look for the rapper to have a "little beef" with Vince, according to series creator Doug Ellin. He told EW.com Eminem's scene will take place "at a platinum record party for his album."

Aguilera, meanwhile, will perform on the episode. She'll be "doing a favor" for Ari, Ellin says, as he hyped the September 12 finale as rich in guest stars. It will also include:

• Minka Kelly
• John Cleese
• Drew Brees
• Ryan Howard
• Kevin Love
• Jordan Farmar
