John Luke wed his fiancee, Mary Kate McEacharn, on Saturday, Us Weekly reported.
"I had an amazing time!" John Luke told Us in a statement.
"It was one of the best days of my life!" added the bride. "It was everything I hoped it would be and more."
The couple reportedly got married at the Robertson family's farm outdoors in West Monroe, LA, surrounded by 800 family and friends. Willie Robertson officiated the ceremony and surprised guests with performances by a Mariachi band.
The reception boasted music by a local band as well as a barbecue feast -- complete with grilled chicken, mini tacos and hamburgers, shrimp and brisket sliders -- followed by dessert featuring cronuts and a white six-tier cake adorned with flowers at the reception.
"[Mary Kate] wanted it real fun, real casual, and she wanted flowers to be a big central point of it all," wedding planner Bethany Sigrest told the magazine.
John Luke and McEacharn, both 19-years-old, got engaged in October 2014 after dating since March 2013. The pair met in 2010 at a Christian summer camp, and John Luke had to persistently keeping asking McEacharn out before she finally accepted his offer. John Luke had told Us that he knew McEacharn was "the one" right off the bat.
John Luke's parents Willie and wife Korie Robertson married at a young age as well. John Luke had expressed how he's always admired his parents' relationship and envisioned a similar life for himself.
John Luke and McEacharn will reportedly both be attending Liberty University in the fall, as McEacharn pulled herself out of Louisiana Tech to plan the wedding.
