Miley Cyrus will be at the Grammys on Sunday. It was confirmed by Jack Sussman, CBS’ executive vice president of specials, music, and live events in an interview with Entertainment Weekly.
The article didn't really make it clear if Miley will be performing or not, but I think there's a good chance she will be.
The Grammys are Sunday, February 10, 2008 at 8pm on CBS. Other featured guests include Alicia Keys, Carrie Underwood, Prince, Rihanna, John Legend, Fergie, Tina Turner, Beyonce, and Nelly Furtado.
