'Duck Dynasty' star Willie Robertson was ready to get in on the holiday fun at the 'CMA Country Christmas' on Monday night (Dec. 2). Robertson  joined Luke Bryan to perform the song, 'Hairy Christmas,' from the Robertsons' debut holiday album, 'Duck the Halls: A Robertson Family Christmas.'

Bryan, who also appears as a guest vocalist on the album, put on a bow tie for the hilarious tune. Prior to their performance, he commended the entrepreneur-turned-TV-star on his fresh-smelling beard - a fitting introduction for their comedic performance.

Bryan isn't the only  star who appears on 'Duck the Halls.' George Strait, Josh Turner and Alison Krauss also lend their vocals to the album, which includes both classic songs such as 'Silent Night' and 'I'll Be Home for Christmas,' and some light-hearted tunes, including 'Ragin’ Cajun Redneck Christmas.'
