It's the classic story of: boy swipes right on girl, girl swipes right on boy. They chat, they meet, they fall in love. Who would have thought on that first date, that a little over a year later, they would be getting married? I think they knew...
After buying their first home in July, they decided that they couldn't wait any longer to be Husband and Wife. As Harry says: "When you realize you want to spend the rest of your life with somebody, you want the rest of your life to start as soon as possible." And that's exactly it.
They know it is a little last minute (you know how spontaneous these two are!), but the love birds would LOVE for you to be able to join them to celebrate their marriage in Las Vegas!
