Prince Harry is going to King Charles' Coronation - but he won't be sticking around for long.
Buckingham Palace announced on Wednesday that Harry will be part of the congregation inside Westminster Abbey on May 6 to see his father and Queen Camilla being crowned.
The Duke of Sussex will be attending on his own, as wife Meghan Markle has decided to remain at home in California with their children, Prince Archie and Princess Lilibet.
According to insiders, Harry was cutely aware that the historic occasion will be "pretty much the most important day" of the King's life and knew he would always have regrets if he turned down the opportunity to be there.
It's been claimed that Harry will only attend the Coronation ceremony itself and no other royal events on a 'fairly quick' trip to the UK next month.
Here is a look at all of the other exciting events he will miss.
The King's Procession and Coronation Procession
The main event will take place inside Westminster Abbey on Saturday 6 May.
Charles and Camilla will arrive in a procession from Buckingham Palace, known as "the King's Procession".
This stretches just 1.3 miles, which is around the quarter of the length of the late Queen's five mile celebration in 1953.
The Coronation service, which will begin at 11am, is being conducted by the Archbishop of Canterbury and will reflect the monarch's role today and look forward to the future.
Prince George and seven other boys named Pages of Honour, who are the sons of royal friends and Camilla's grandsons, will 'attend their majesties' during the service.
After the service they will return to the palace in a larger ceremonial procession, known as "the Coronation Procession".
Newly crowned Charles and Camilla will make their way back from Westminster Abbey via the tried and tested route of Parliament Square, along Whitehall, around Trafalgar Square, through Admiralty Arch and down The Mall back to Buckingham Palace.
The Coronation Procession will include Armed Forces from across the Commonwealth and the British Overseas Territories, and all Services of the Armed Forces of the United Kingdom, alongside The Sovereign's Bodyguard and Royal Watermen.
Harry is not expected to take part in either of the processions to and from the palace.
The balcony appearance
Royal sources have claimed that only working royals will be allowed on the Buckingham Palace balcony, showing Charles' vision of a slimmed down monarchy.
Detailed plans seen by The Mirror reveal how the King has chosen to say thanks for the nation alongside a select few royals who have dedicated their lives to public service.
Within the final group of 15 will be a number of royals, including Prince William, Kate Middleton and their three children.
But there is no place for Harry on the famous balcony
Future king and queen, the Prince and Princess of Wales, will appear with their three children - Prince George, nine; Princess Charlotte, seven and Prince Louis, four.
The final group of 15 shows there is no place for Harry and Meghan if they do decide to attend, but inviting their children up could be seen as an olive branch.
Rumours of Harry's demands to be included on the balcony are said to be "wide of the mark", according to palace insiders.
A source with knowledge of the plans said: "The King has been very clear who he wants to represent the monarchy.
"There is little room for sentiment, this is a State occasion, not a family occasion and it is right that only the working members of the family are there at the big public moment."
Coronation Big Lunch
On the Sunday, people across Britain will take part in the Coronation Big Lunch, during which neighbours and communities will be invited to share food and fun.
The Queen Consort has been patron of the Big Lunch since 2013, and thousands of events are expected to take place in streets, gardens and parks in every corner of the UK.
The Government announced that the Prime Minister will host a Big Lunch at Downing Street and that guests will include community volunteers from across the country.
Meanwhile, the Culture Secretary has called on the public to showcase their local celebrations on a digital map.
Members of the Royal Family are expected to take part in some of the big lunches around the country, but it doesn't look like Harry will have time.
Coronation Concert
A star-studded Coronation Concert will take place at Windsor Castle on the Sunday night - with the palace promising "global music icons and contemporary stars".
The audience will include members of the Royal Family, volunteers from the King and Queen Consort's charity affiliations and several thousand lucky people who got tickets in the public ballot.
The show will feature a world-class orchestra playing interpretations of musical favourites fronted by "some of the world's biggest entertainers, alongside performers from the world of dance", the palace said.
The performances will be supported by staging and effects located on the castle's East Lawn and will also include a selection of spoken word sequences delivered by stars of stage and screen.
The million dollar question is who will be performing - but organisers have remained very tight-lipped on the bill so far.
Lionel Richie and Take That widely expected to take to the stage, while Ed Sheeran, Adele, Sir Elton John, Harry Styles and the Spice Girls have all reportedly declined invitations to appear.
The Coronation Choir, a diverse group that will be created from the nation's keenest community choirs and amateur singers from across the UK, such as refugee choirs, NHS choirs, LGBTQ+ singing groups and deaf signing choirs, will also make an appearance.
The Coronation Choir will appear alongside The Virtual Choir, made up of singers from across the Commonwealth, for a special performance on the night.
The palace said the centrepiece of the coronation concert, dubbed "lighting up the nation", will see the country join together in celebration as landmarks across the UK are lit up using projections, lasers, drone displays and illuminations.
The Big Help Out
There is a special additional bank holiday on the Monday, with members of the public are being urged to take part in 'The Big Help Out'.
In recognition of the King's concern for strengthening local communities, the palace said the big help out "will encourage people to try volunteering for themselves and join the work being undertaken to support their local areas".
Organised by The Together Coalition and a wide range of partners such as The Scouts, the Royal Voluntary Service and faith groups from across the UK, the big help out aims to highlight the positive impact volunteering has on communities.
The King and Queen Consort hope that the impact of the Big Help Out will be felt across the country, creating a lasting legacy and the recruitment of more volunteers.
Harry will likely be back home in California during this special day to round off the bumper Coronation weekend.
