Eminem has got 10 chances of winning a Grammy this weekend but he's worried he won't get any.
The rap star is leading the list of nominations and already has 10 Grammys to his name, but it seems the doubts are still creeping in.
He's up for Song of the Year for 'Love the Way You Lie', as well as the coveted Album of the Year trophy for Recovery.
But his rapper pal Royce da 5'9" told 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 has a different opinion, "I think he's gonna win. We're rooting for him."
Meanwhile Eight-time Grammy winner Barbra Streisand will give a rare, live performance at the Grammys.
The 68-year-old actress and singer is also nominated for a trophy for the best traditional pop vocal album for "Love Is the Answer".
Streisand only performs sporadically, but her last tour of Europe and the US in 2006/07 set box-office records.
