"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. God has truly blessed us."

A photo posted to McEacharn's Instagram account shows John Luke holding a sign that reads "Future Mrs. Robertson," with the bride-to-be showing off her engagement ring. A caption reads: "Happy Birthday to the boy I'm going to marry."

He posted the same picture to his own Instagram account along with the caption, "She. Said. Yes."
