Behold: The royal wedding invitations are here, and they look as fancy as you'd expect.

Excuse us if we seem a little eager to collect the mail every day from now on, because Kensington Palace has just confirmed that the official wedding invitations for Prince Harry and Meghan Markle’s upcoming nuptials have been sent.

Yes, that’s right, the most important people from all over the world should soon be receiving a personalised invite to watch the 36-year-old Suits actress and the 33-year-old Prince tie the knot on May 19.

Following tradition, according to Kensington Palace, the invites have been issued on behalf of Harry’s father, Charles, Prince of Wales, even though it was the Queen herself who had to give formal permission for Harry to marry the American actress.

A reported 600 guests have been invited to attend the pair’s service at St George’s Chapel at Windsor Castle, and will then enjoy a lunchtime reception hosted by Her Majesty The Queen at St George’s Hall.

Later the same night, 200 of Harry and Meghan's nearest and dearest will enjoy a nighttime reception hosted by Prince Charles at Frogmore House.

We don't know about you, but the thought of sitting and smiling through a ceremony and no less than TWO wedding receptions is exhausting us already.

But what's more exhausting, perhaps, is the painstaking effort put into the couple's invitations, which, following royal traditional, were been designed by Barnard and Westwood.

Just one woman, Lottie Small, printed all of the invitations using a process known as die stamping. The machine used to print the invites was made in the 1930s and is affectionally nicknamed 'Maude', which seems like an appropriately royal name.

Kensington Palace also shared a video of Lottie working hard to create the invites, which feature black and gold ink, the Three-Feathered Badge of the Prince of Wales and gilded edges.

Fancy.

For that extra, personalised touch, each guests's name was then individually added by a calligrapher.

It's not yet known which famous faces have officially made the cut for the big day, but rumour has it the Spice Girls, Elton John and three of Prince Harry's exes - Cressida Bonas, who he dated for two years, Chelsy Davy and British singer Ellie Goulding - are all on the guest list.

Some of Meghan Markle's celebrity friends, including Priyanka Chopra and designer Misha Nonoo, are also expected to be in attendance.

While former US President Barack Obama and his wife Michelle are also speculated to be on the list, the soon-to-be-wedded duo may have had to leave them off their invite list so as not to 'snub' the current President, Donald Trump.

The invite details are the latest in a string of confirmations from the palace: earlier this week, the details of the couple's wedding cake and baker of choice were released.
