If you're not in the Christmas spirit, then this holiday performance from Kelly Rowland and Michael Buble should fill you up with yuletide fuzzies. The duo teamed up for a jazzy rendition of the Irving Berlin song 'White Christmas' (as sung by the late Bing Cosby).

The clip is from the crooner's U.K. holiday special 'Michael Buble: Home For Christmas.' Buble was looking fierce in his navy suit and tie, while Rowland looked like a swan in her short white feathery dress. The lovely pair sung the holiday classic together with doo-wop group Naturally 7.

Buble and K.Row even cut a rug during a small break in the song as the big-band orchestra played on. We were amazed at how Rowland was able to twirl in those 7-inch pumps. You go girl!

We can't get enough of these two beautiful-looking vocalists. Our Christmas wish is that Buble and Rowland team up for a catchy pop song soon.

Buble is certainly seeing a lot of green this Christmas. The singer's holiday opus, 'Christmas,' is poised to become the second-biggest selling album of 2011. So far, he's sold 1.52 million copies and is expected to push 2.4 million units out the store by year's end.
