A camouflage-clad bride and groom got a little advice from a bewhiskered witness on their wedding day: “Duck Dynasty” star Willie Robertson.

“Love each, forgive each other,” he said, noted the Pine-Richland Patch. “Watch my show from the other night when my mom and dad got remarried, that should give you all the basics you need to know.”

Robertson, who was appearing at Field & Stream store near Pittsburgh to sign autographs Saturday, popped in for the nuptials of Mehgan Cook, who sported a camouflage sash on her dress, and Charlie Miller, who was completely clad in camo gear.

The two hadn’t planned on marrying at the store but Cook said they were eager to meet Robertson. “I was going to cancel the wedding ’cause I heard Willie was coming,” Cook told KDKA-TV.

Instead Cook’s mother came up with the idea of a wedding at the store — and Field & Stream invited the Beaver Falls couple to get married there after Ruth Bell told them all about her daughter’s love for the show, the Patch notes.

And they got a surprise when Robertson appeared during the ceremony, tapping them on the shoulders. Miller called the experience like “waking up on Christmas morning when you’re a little kid,” the Patch said. “It was definitely not expected at all,” Cook added.

“That’s a first for me, it’s good to be a part of that,” Robertson said. “They look like my kind of folks with the camouflage. That was cool.”

Cook said she had been engaged to another man in 2009, but he died in a car crash one week before the wedding.

Cook, who had attended school with Miller, got reacquainted with him at a memorial service for her former fiance, and they eventually began dating.

And how much do the bride and groom love “Duck Dynasty”?

Well, they named their youngest son, six-month-old Jase, after Robertson’s older brother, the Patch reports.. Cook, 26, also has two children from a previous relationship.

“When the show comes on, it’s lights out in the living room and we all sit on the couch and watch and don’t move,” Cook told the Patch.
