Scotty McCreery croons for ‘Duck Dynasty’s’ Sadie Robertson

The “Duck Dynasty” clan is getting closer to an off-screen friend: Scotty McCreery.

The country crooner and “American Idol” winner has been hanging out a lot with the family Robertson, whose bearded patriarchs waded to fame on A&E’s reality smash.

On Monday, McCreery revealed on Twitter that he’ll join the clan for a “Duck Cruise” tour that will hit Key West and Cozumel next summer.

Two weeks ago, “The Trouble With Girls” singer was the surprise entertainment at the 16th birthday of Sadie Robertson, the daughter of Duck Commander owner Willie Robertson. He serenaded Sadie with his hit, “See You Tonight.”

Sadie tweeted a photo of herself with McCreery after the family went mudding, adding: “This boy made my birthday the best day of my life!”

Must be nice to have a dad who can wangle a top-selling recording act for your birthday party.

At the moment, it’s unclear whether McCreery will turn up in future “Duck Dynasty” episodes. But the lad does seem eager to get to know the Robertsons, and that’s giving fans something new to talk about.

“See You Tonight.” Hmm.
