It is set to be the wedding of the year.
And today, Prince Harry and Meghan Markle announced that thousands of members of the public will be invited to Windsor Castle on their big day.
The pair want the special occasion "to be shaped so as to allow members of the public to feel part of the celebrations too," Kensington Palace said.
The wedding will be a "moment of fun and joy" that will reflect the values and characters of the bride and groom, a spokesperson added today.
Harry, 33, and Meghan, 36, will invite 2,640 members of the public into the castle's grounds to watch their arrivals - and those of their guests.
The lucky attendees will also get to see the carriage procession as it departs from the royal residence, where the couple are tying the knot.
But who will be among the thousands invited? Could it be you?
Well, if you are a young person who has shown "strong leadership" or someone who has served your community, you could be in luck.
Among the attendees will be 1,200 people from "every corner" of the UK, who have been nominated by nine regional Lord Lieutenant offices.
The Lord Lieutenant is the Queen's personal representative in each county.
Harry and Meghan have asked that the people chosen are from a "broad range of backgrounds and ages, including young people who have shown strong leadership, and those who have served their communities".
If you work for a charity or organisation with which Harry and Meghan have a close association, you could also end up bagging yourself an invite.
The same can be said for those who are community members of Windsor Castle or members of The Royal Households and Crown Estate.
And if your child attends The Royal School, Great Park, Windsor, or St George's School, Windsor Castle, they could be invited to the big day.
A Kensington Palace spokesperson said this morning: "Prince Harry and Ms. Meghan Markle have said they want their wedding day to be shaped so as to allow members of the public to feel part of the celebrations too.
"This wedding, like all weddings, will be a moment of fun and joy that will reflect the characters and values of the bride and groom.
"In addition to the carriage procession in Windsor, they have today shared some further details of how the public will be involved on May 19th.
"Prince Harry and Ms. Markle have invited 2,640 people into the grounds of Windsor Castle to watch the arrivals of the bride and groom, and their wedding guests, at the chapel and to watch the carriage procession as it departs from the castle."
The 2,640 people who could be invited:
- 1,200 members of the public from every corner of the United Kingdom will be nominated to attend by nine regional Lord Lieutenant offices. The couple has asked that the people chosen are from a broad range of backgrounds and ages, including young people who have shown strong leadership, and those who have served their communities.
- 200 people from a range of charities and organisations which Prince Harry and Ms. Markle have a close association with, including those which Prince Harry serves as Patron.
- 100 pupils from two local schools: The Royal School, Great Park, Windsor and St George's School, Windsor Castle – both of which have a strong affiliation with the Windsor Castle community.
- 610 Windsor Castle community members, including residents of Windsor Castle and members of the St George's Chapel community.
- 530 Members of The Royal Households and Crown Estate.
Harry and Meghan announced their engagement to a flurry of excitement in November, after the prince popped the question over roast chicken.
Their wedding is expected to attract attention from around the world.
