The countdown has well and truly begun.
In less than three weeks, Prince Harry and Meghan Markle will tie the knot in spectacular style at Windsor Castle.
But there are some things you might not know about the much-anticipated big day.
Read on for 10 facts about the Royal Wedding.
Donald Trump has not been invited – nor has British Prime Minister Theresa May
As well as leaving the Prime Minister and other politicians off the guest list, Harry and Meghan have chosen not to invite the US president or his predecessor, Barack Obama, deciding that the event is not a state occasion.
Meghan’s father will give her away
Thomas Markle will proudly walk his daughter down the aisle of St George’s Chapel in Windsor, despite having to perform the daunting duty in front of a global television audience. The former TV lighting director usually lives a quiet life in Mexico.
The $60 million secret
No-one knows exactly how much the event is costing, but one wedding planner has estimated it at a staggering £32 million – that’s almost AU$60 million – with secret security accounting for most of the cost.
The Queen’s special role
Six hundred guests will gather after the ceremony in Windsor Castle’s majestic, medieval St George’s Hall to be hosted by the Queen at a lunchtime reception.
The wedding cake has to be baked just in time
Harry and Meghan’s lemon elderflower cake, with its fresh buttercream icing, will have be crafted shortly before May 19 by their chosen baker, Claire Ptak, unlike a traditional fruit cake which can be made well in advance.
The after party
The newlyweds will dance the night away with 200 guests in the sanctuary of Frogmore House, which stands about half a mile south of Windsor Castle in Windsor Home Park.
The rings will be made from THIS
Royal wedding rings are traditionally made from Welsh gold. Since the custom was started by the Queen Mother in 1923, Welsh gold has been used for royal brides ever since.
The secret ceremony ahead of the wedding
Meghan has been both baptised and confirmed in the Church of England ahead of her religious wedding. The Archbishop of Canterbury, who performed the secret service, said: ‘It was very special, it was beautiful and sincere.’
The Archbishop is worried
The Most Rev Justin Welby, who will officiate at the ceremony, has admitted that worries about dropping the ring have been dominating his preparations.
The prince had to ask permission to marry
Because of the Succession to the Crown Act, the first six people in the line of succession must ask for the Queen’s consent. She said yes of course, but was unlikely to ever refuse except on the advice of the Prime Minister.
