Leona Lewis has recorded the lead song for director James Cameron's much anticipated new movie, Avatar.

The former X Factor winner's track, entitled 'I See You', has been produced alongside James Horner and Simon Franglen.

They are the same production duo responsible for Celine Dion's 'My Heart Will Go On', which was included in Cameron's 1997 epic, Titanic.

'I See You' will play over Avatar's closing credits.

Set to release in December, the big-budget movie tells the story of a battle raging in a far-away world called Pandora.

The film utilises a number of groundbreaking new filmaking techniques and will be screened in both 2D and 3D.

As previously reported, Lewis is due to embark on her debut UK tour next summer.
