The "Duck Dynasty" stars will have a very busy weekend ahead as the Robertson family prepares for the wedding of Willie and Korie's 19-year-old son John Luke to his 18-year-old fiancée Mary Kate McEacharn this Saturday, June 27. 

The couple got engaged when John Luke proposed during his 19th birthday celebration last October. His younger sister Sadie, who was still competing in ABC's "Dancing With the Stars" at that time, gushed about the engagement in her previous interview with Us Weekly, saying that she is very excited to welcome Mary Kate in their family and be her bridesmaid at the wedding. 

John Luke and Mary Kate first met at a Christian summer camp back in 2011, and continued their friendship when they became classmates in a chemistry class at the Ouachita Christian School. They began dating in March 2014, and got engaged in October that year. 

Mary Kate admitted that John Luke is her first boyfriend, and he was the one that God sent to be with her for the rest of her life. 

They decided to have several online wedding registries to help their guests pick their wedding gifts. The registries also shared more information about the upcoming wedding, including the venue of the ceremony in Louisiana, where they both live. 

Based on their entries on the bridal registry websites of Bed, Bath, and Beyond and West Elm, the young couple wants to receive practical items like bakeware, drinking glasses, and other kitchen utensils, among others. 

The groom's mother Korie also revealed several details about the wedding in an interview with FOX411 last month, saying that the couple's planned summer wedding is being taken care of. 

"We're meeting with the wedding planner Monday and things are coming along," the mother of the groom shared. 

Korie also admitted that they are struggling with finalizing the guest list, saying: "The hardest part is figuring out the invite list; we've got big families." 

The couple's engagement party was featured in the premiere episode of the latest season of "Duck Dynasty" on TLC.
