X Factor winner Leona Lewis has recorded the signature song for James Cameron's eagerly anticipated science-fiction film Avatar.
Titled I See You, Leona's track will play during the closing credits of the film.
Out on December 18, it has been in development for 12 years and uses state of the art technology to create a 3D computer-generated world.
I See You, which hits shelves on December 14, has been produced by the same team behind Celine Dion's My Heart Will Go On which accompanied Titanic.
