Miley Cyrus shows off her new hair 'do.

Miley Cyrus showed off her new dark hair at the World Premiere of Walt Disney Pictures' "Hannah Montana/Miley Cyrus: Best of Both Worlds Concert Tour" at the El Capitan Theater in Hollywood last Thursday, January 17th. She was wearing an Alberta Ferretti cocktail dress, simple black pumps and a black clutch. Ashley Tisdale was also at the premiere, I'll post a picture of the two of them later...I'm still looking for it.
