Caitlyn's firstborn, fellow Swiftie, and best friend for the past 17 years, it was no question that Mack would be by her side as she said "I do".

Matt's sister and very first friend. They have always been incredibly close, growing up riding horses and skiing together. Laura has always been there for Matt, and he is grateful to have her be part of his big day. (Caitlyn is very excited to have a new big sister that comes along with a pony or two!)

Matt and his cousin John have always shared a close bond. They grew up like brothers playing many sports and working jobs together. Matt is excited to have John as his best man!

Matt's brother-in-law always knows how to have a good time. Typically the best dressed in the room, Matt will count on him to make sure he's looking extra dapper for the big day!
