John told Us Weekly about why he wants to marry young, "I know my parents married young as well, and they have always been examples of what 'could be' to me. 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."
Congrats to the happy couple!
John's sister Sadie has been one to watch on DWTS, and in case you missed last week's episode, Alfonso Ribeiro did the Carlton! Watch it here.
