But the hip-hop star doubts he'll win big at the prizegiving on Sunday (13Feb11), according to his rapper pal and Shady Records recruit Royce da 5'9".
Royce tells MTV.com, "It's funny, I just had the conversation with him about it. He doesn't think he's gonna win anything. He wouldn't bet me, though. But I think he honestly thinks he's not gonna win. Which I think is ridiculous."
But Royce insists he has full confidence in his mentor, adding, "I think he's gonna win. We're rooting for him."
Eminem will also take top billing as a performer at the Grammys, to be held at Los Angeles' Staples Center.
