Is there anything the stars of "Duck Dynasty" can't do? Not only are they the faces of the hit A&E show, but they have taken over country music. Willie Robertson hit the stage with Luke Bryan and it was one of the best--and funniest --performances during the "CMA Country Christmas" special.

Willie hit the stage with Luke and made us all laugh with “Hairy Christmas.” They were making a joke about Willie’s beard, and Jennifer Nettles-- the host for the evening-- bent down to smell it. (She said it smelled lovely, in case you were wondering.)

Willie recently spoke about performing with Luke and said: “It’s quite an honor to be invited here with our Christmas album out now, 'Duck the Halls,' we really wanted to show up when we could actually contribute something.”

Back in November, the stars gave Miley Cyrus a run for her money when they appeared at the 47th Annual CMA Awards, joining Carrie Underwood and Brad Paisley on stage for a rendition of “Blurred Lines.”
