Celine Dion

Oscar's heart still goes on for Céline Dion.

Sources tell me that Dion has been booked to perform at this year's Academy Awards. The Canadian crooner will sing during a tribute to legendary composer Ennio Morricone, who will be receiving an honorary Oscar at the Feb. 25 ceremony.

I'm told lyrics have been written for Morricone's score for Once Upon a Time in America just for Dion. "The lyrics have never been heard before," one source says.

Another source says that the song will probably be included on Dion's upcoming English-language album to be released sometime in the fall. A French album is expected to hit stores this April.

Dion is reportedly going to be included on a Morricone tribute album later this year, along with Yo-Yo Ma, Bruce Springsteen and Metallica.

This will be Dion's fifth time performing at the Oscars. While her career in movies is highlighted by the infectious "My Heart Will Go On" from Titanic, her outfit on the red carpet of the 71st annual Academy Awards in 1999 has become one of the more infamously panned getups. She wore a reverse white tuxedo from John Galliano with a matching fedora. No word on who will be dressing her this time around.

Dion's rep did not return calls.

While no performers have been officially announced, Awards producer Laura Ziskin announced earlier today that George Clooney, Cameron Diaz, Hugh Jackman and Eva Green will be presenters on the big night.
