KISSMAS Music: Demi Lovato & Kelly Clarkson Duet “Have Yourself a Merry [VIDEO] Little Christmas” at Z100 Jingle Ball

During the 2011 Z100 Jingle Ball event held Friday December 9th in New York, Demi Lovato had the opportunity to share the stage with her musical idol, Kelly Clarkson for a duet of the holiday classic, "Have Yourself a Merry Little Christmas."

Clarkson started as confetti fell from the rafters of the stage. Then Clarkson proudly introduced Demi, to a sold-out house at Madison Square Garden.

“We’ve been dying to sing together!” added a humbled Lovato. And from the sound of things they probably will. Following the event, Lovato and Clarkson tweeted about doing it again in the future.

“@ddlovato girl we have got to sing together again!” Clarkson tweeted. “You have such a powerful and beautiful voice! I love your spirit.”

Lovato added, “Oh my God….. Oh my God…. Oh my God … #shaking,” she wrote. “I. Just sang. With Kelly. Clarkson. #ahhhhhhh.”
