Duck Dynasty‘s John Luke Robertson tied the knot with Mary Kate McEacharn Saturday night in front of a large crowd of family and friends, his rep confirms to PEOPLE. The reality star popped the question last October to McEacharn on his 19th birthday by presenting his wife-to-be with a photo album that included a picture of her engagement ring on the last page. Life According to Duck Dynastys Uncle Si “Our relationship is focused on God,” he told Entertainment Tonight last year. “The divorce rate is 50% for everyone. But, for Christians who are active in their faith, it is 35% less than that.” Before swapping vows on Saturday, Robertson posted a fun video of him “headed to the chapel,” and two weeks ago, the new groom posted a cute picture of him and McEacharn with a pair of adorable goats. “You have GOAT to be kidding me! We are almost married!” he captioned the photo. Close
