Christina Aguilera and Eminem are the latest stars to sign up for a cameo appearance in hit show Entourage.

Jessica Simpson and Zac Efron have previously filmed guest slots for the drama, and now Aguilera and rapper Eminem are set to appear in the upcoming series opposite Adrian Grenier.

Eminem has already filmed his scenes, with Entourage creator Doug Ellin telling Entertainment Weekly he will appear "at a platinum record party for his album (Recovery), which by the time this airs will be platinum, I'm sure. He has a little conflict - a little beef - with Vince (Grenier)."

Dirrty hitmaker Aguilera is set to sing on the show, with Ellin adding, "She's doing a favor for Ari (Jeremy Piven) and performing at a party for him."
