The ultimate Duck Dynasty-themed wedding! Willie Robertson surprised Duck Dynasty super-fans Mehgan Cook and Charlie Miller at their Saturday, Aug. 17 wedding. The 41-year-old A&E star made an appearance at the couple's ceremony, which was held inside the Field & Stream store in Cranberry Township, Penn.

Robertson strived to make the bride's wedding was extra special after she suffered a devastating loss four years ago. Cook was engaged to marry the father of her two young children -- but a week before the wedding date, her fiance was killed in a tragic car accident.

Given a second chance at love, Cook met Miller. Sharing a mutual passion for the smash reality show, the pair tied the knot in a special Duck Dynasty-inspired wedding -- where the bride wore a strapless white gown with a camouflage print belt, and the groom donned a camouflage T-shirt, black pants and camo boots.

After the ceremony, Robertson met the couple's adorable 5-month-old son, Jase, who was named after Robertson's older brother, who also stars in the show. Robertson happily obliged with a group photo with the wedding party and signed autographs for fans.

This isn't the first Duck Dynasty wedding Robertson has attending this year. On the Aug. 14 premiere of Season 4, he attended his parents Phil and Kay Robertson's vow renewal ceremony.

After 49 years of marriage, the couple decided to renew their vows so they could finally have a proper ceremony. "You are my best friend, and I love you dearly, and I'm going to be with you for the long haul, until they put me in the ground," Phil said. "Good?" His wife replied, "Perfect."
