Duck Dynasty's John Luke Robertson is off the market!

Robertson, 19, married Mary Kate McEacharn, also 19, on Saturday at his family farm in Louisiana, Us Weekly reports. More than 800 guests attended the ceremony, which was officiated by his father Willie.

"I know my parents married young as well, and they have always been examples of what 'could be' to me," Robertson told Us last year. "Fast-forward 22 years and they are more in love than ever, and I hope Mary Kate and I are the same way in the years to come."

Robertson proposed to McEacharn last October. They have been dating since early 2013, after meeting at a Christian summer camp three years earlier, according to Us. They will both be attending Liberty University in the fall.
