James Cameron and James Horner helped propel Celine Dion's career into the stratosphere, can they do the same for Leona Lewis?

Atlantic Records announced today that Lewis, whose new album "Echo" is released this week, will sing the title track "I See You" for Cameron's long awaited new film "Avatar."  Written by Academy Award winner James Horner, the single will be included on the film's score soundtrack which will be released on Dec. 15.

Horner won two Oscars for his previous collaboration with James Cameron, "Titanic."  One was shared with lyricist Will Jennings for the global smash "My Heart Will Go On" which help sell 30 million "Titanic" soundtrack worldwide (only 690,000 singles were available in the U.S).  The single made the already popular Dion a household name and drove countless repeat ticket sales for fans who just couldn't get enough of the haunting love theme.

That sort of lighting rarely strikes twice, but Lewis will take her chances. The "X-Factor" winner's first album "Spirit" and her debut single "Bleeding Love" both hit No. 1 in the U.S., but her notoriety has stalled on this side of the Atlantic.  if "I See You" can land an Oscar nomination for Best Original Song it will be another stepping stone in the Brit's career.  Strangely, the release of "Echo" was not delayed so it could include "You."

"You" will have stiff competition in the always difficult to crack song category.  New tunes from "Nine," "The Princess and the Frog," "Up in the Air," "Where The Wild Things Are" and "Crazy Heart" are all assumed to be frontrunners for a nomination.

No word from 20th Century Fox or Atlantic Records on when fans will get a chance to preview the new track before "Avatar" his theaters on Dec. 18.
