Scotty McCreery performs at 'Duck Dynasty' birthday party

"Duck Dynasty" daughter Sadie Robertson got her Sweet 16 wish come true: a serenade from "American Idol" winner Scotty McCreery.

During the party, which featured a "redneck red carpet," McCreery sang a duet with the show's star Willie Robertson and even danced with the birthday girl, Us Weekly reports.
