Except, Eugenie's fiancé's name is Mr Jack Brooksbank.
Brooksbank described his bride-to-be as a "bright shining light", while Eugenie said: "Jack's the kind of guy, you know, when you're lost at a party and you can't find anyone to talk to, and you start panicking and you need help?"
Well known faces predicted to attend the second royal wedding of the year include singer Ellie Goulding and fiance Caspar Jopling, supermodel Cindy Crawford, David and Victoria Beckham, Harry's exes Cressida Bonas and Chelsy Davy, model Cara Delevingne, singer James Blunt and wife Sofia Wellesley, and George and Amal Clooney.
"The monarch and her family are part of the shop window for Great Britain, and at the end of the day anything that goes on that creates people wanting to come to this part of the world - come and see what goes on in Windsor - we're very happy for that", he said. Some people think that not only is Eugenie trying to copy her cousin, but that she's trying to one-up him as well.
The event comes nine months after the couple, who have dated for seven years, publicly announced their engagement at Buckingham Palace. This week, the members of the bridal party were revealed, confirming Princess Beatrice's role as Maid of Honour for her close friend and confidante.
The ninth-in-line to the throne is following in the footsteps of the Duke and Duchess of Sussex, who also chose the venue for their wedding in May. It was not certain whether the 92-year-old queen's husband Prince Philip, 97, who no longer carries out official duties, would be present.More news: Twitter reacts to Tua Tagovailoa putting up video game numbers against Arkansas
Police teams have been meticulously checking and sealing water drains near the castle, and sniffer dogs are checking for explosives in the royal-themed shops, restaurants and tea rooms frequented by tourists.
It's reported that Eugenie has asked guests not to bring their cell phones or any cameras because "photography is not allowed in St George's Chapel or Windsor Castle".
