Leona Lewis will join the ranks of Celine Dion as a multi-octave voice diva to belt out a theme song in a James Cameron film soundtrack.
Lewis will sing "I See You" for the soundtrack of the long-awaited sci-fi epic, Avatar. The song is composed by James Horner, who also worked with Cameron on the Titanic and Aliens soundtrack.
Avatar stars Sam Worthington, Zoe Saldana, Sigourney Weaver and Michelle Rodriguez.
The 3-D warfare film is slated to hit theaters Dec. 16, while Lewis' second studio album, Echo drops today. --Caroline Acosta
