The curtain may be going down on Celine Dion’s legendary live show in Los Vegas, but E! sources say that the four time Academy Awards headliner has been booked for a fifth appearance.

C.D will sing during a tribute to composer Ennio Morricone, who is slated to receive an honorary Oscar at the ceremony scheduled for February 25th.

Supposedly, the 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.

And yet another E! snitch says that the song will be included on Celine’s new English-language album to be released sometime in the fall. The singer’s French album is expected to hit stores this April.

No word from Team Celine.
