Kelly Clarkson: Recording a Duet with Demi Lovato!

Kelly Clarkson gives us a smooch while posing with a fake mustache backstage at Y100 Jingle Ball 2011 held at the BankAtlantic Center on Saturday (December 10) in Sunrise, Fla.

The 29-year-old singer hit the stage during the annual show to perform songs off her new album Stronger as well as some of her greatest hits.

When asked what she wants Santa to bring her this year, Kelly told JustJared.com “a hot man!”

“I actually just like really funny guys. I actually don’t like really hot guys because they usually take more time in the bathroom than I do,” she added.

Kelly also filled us in about recording a duet with Demi Lovato, who she performed with at Z100′s Jingle Ball the night before.

“It’s a song a friend of mine wrote. It’s killer and I’ve been wanting to sing it for a while. It’s very like urban, pop/rock, and we both like that,” Kelly said. “It’s my normal anthem, shove it in your face [type of song].”
