Rascal Flatts brought their form of perfectly harmonious Christmas cheer with a lively rendition of 'Jingle Bell Rock' to the 2013 'CMA Country Christmas' special on Monday (Dec. 2). 

Gary LeVox, Jay DeMarcus and Joe Don Rooney wore dark burgundy and black, looking polished and coordinated in their festive and classy outfits.

Behind the Flatts, a large brass section brought a jazzy feel to the Christmas classic, incorporating saxophone, trombones and many other instruments that made the upbeat song even more danceable.

The 'CMA Country Christmas' stage was beautiful with huge Christmas trees, wrapped gifts and -- of course -- glittery Christmas lights, and LeLVox ended the song with a hearty "Merry Christmas, everybody!"

The jingle hop has officially begun!
