Celine Dion joined forces with Michael Buble to perform her rendition of the John Lennon’s 1971 classic ‘Happy Xmas (War Is Over)’ during the Christmas In Hollywood television special, which aired Thursday (December 10).

It is such a pleasant surprise seeing Celine slaying effortlessly singing live. I mean she has been lipsynching her ass off for God knows how long. Great vocal performance!

Buble also sounded great, as usual. His vocals and Celine’s complement each other perfectly. A duet by them will surely slay.

Watch their performance of  ‘Happy Xmas’ below….
