King Charles III's Coronation is almost here and all eyes will be on the monarch as he heads to Westminster Abbey for the official service.
About 2,000 people are expected to pack into Westminster Abbey on May 6 for the spectacle, and some of the lucky ones who have scored an invite have already confirmed they'll be there.
The guestlist will see King Charles and Queen Camilla share the abbey with members of their close friends and immediate families, foreign royals, world leaders, politicians and ordinary folk.
And it turns out the King has a wide selection of celebrity friends. But how many of them will be getting an invite to the prestigious ceremony? Here we take a look inside his circle of famous friends.
Do you wish you were at the coronation? Let us know in the comments...
Ant and Dec
King Charles struck up an unlikely friendship with cheeky Geordie duo Ant McPartlin and Declan Donnelly, after a "surreal" experience in 2015 where they followed him around for a documentary.
The pair also hosted The Prince's Trust Awards and recorded When Ant And Dec Met The Prince: 40 Years Of The Prince's Trust - which saw them stay the night in one of his homes.
Charles invited the pair to stay at Dumfries House in Ayrshire, which was bought by a consortium headed by His Majesty in 2007, where they were greeted by butlers and put in rooms right next to their royal host.
Ant admitted it felt bizarre bumping into King Charles outside his room, with the I'm A Celebrity presenter wearing only in his dressing gown.
Ant said: "I'm stood in a robe, in his house, in the middle of the day. He smiled, I smiled then I did the only thing I could. I slowly backed into my room, closed the door and silently screamed into a pillow..."
Ever the rebels, Ant admitted to making the most of the butler service by ordering lashings of wine.
"We shared a butler and as we were going to bed he asked if we'd like anything else and we asked for two bottles of wine," he continued.
"We then got drunk with our wives but we were very conscious that Charles was down the corridor so as we got louder every now and again one of us would go, 'shush, he's in bed!' It was very bizarre."
Despite being advised otherwise beforehand, the lads found themselves getting a little too excited and "over-familiar" with the future king during production.
"Protocol-wise, we did occasionally forget stuff," confessed Ant. "I did find myself getting a bit over-familiar and grabbing His Royal Highness and slapping him on the back a bit - I had to keep stopping myself."
Luckily for the boys, they needn't have worried about messing up their lines as the Prince struggled to understand their Geordie accents.
"We had no issues with his accent, but I think he may have had a few with mine," added Ant. "I would ask him a question and sometimes he would just smile. Then Dec would ask the same question and get a full answer!"
To show just how close they became, Ant invited Charles to Dec's stag do ahead of his 2015 marriage to Ali Astall.
Unfortunately, the royal turned down the offer of getting drunk with the lads but he did send Dec a handwritten letter and a touching wedding gift.
Dec wrote: "When I got married in 2015, Ant got in touch with HRH. He politely declined the stag do...
"But he did send a handwritten letter to Ali and me as well as a lovely wedding gift - a set of placemats that were all watercolours he'd painted himself."
Later, Charles made a cheeky joke about his Geordie pals "following him around" during a surprise appearance on The One Show.
He recorded a video message for the duo as he was helping launch a joint initiative to help young people secure jobs - the Ant & Dec's Making it in Media project.
Charles said: "I can think of no better duo to help drive this activity than Ant and Dec, who have enjoyed an illustrious career in the media for over 30 years.
"During that time, they've both followed me around, they followed me around while filming a documentary for ITV.
"And they've also played an incredibly generous part in our annual Prince's Trust awards event in London.
"So thank you, Ant and Dec, more than I can ever say, for all your wonderful efforts on behalf of the young people who will be supported by this project."
Star-studded wedding
When Charles and Camilla tied the knot 15 years ago they hosted a wide range of celebrities, including Jilly Cooper, Timothy West, Richard E Grant, Jonathan Dimbleby and Jacob Rees-Mogg's father, William.
Beloved comic Joan Rivers also attended, and broke the rules by sending a wedding gift... sexy undies to Camilla.
She joked it was either that or a trendy grill with a chip pan attachment.
The US comedienne said Camilla 'roared with laughter' when she said she wanted to throw her a lingerie shower.
She said at the time: "She thought it was hilarious and said, 'well send the things'."
Joan, who met the couple through charity events, was very fond of Camilla.
She revealed in 2005: "She's a very earthy, funny woman – you can swear in front of her."
Joan, who died in 2014 aged 81, added: "The people of Britain are going to love her once they really get to know her."
Alan Titchmarsh
TV gardener Alan Titchmarsh counts King Charles as a friend and event stepped in to defend him after one of Prince Harry and Meghan Markle's bombshell interviews, insisting: "I feel for him a lot."
Alan – who is close friends with the royal having done several TV and radio shows with him – said it was "sad" to see what Charles was put through as a result of the Oprah Winfrey interview.
Alan - who previously told how he was boycotting The Crown in solidarity with Charles – said: "He is an amazing man. I feel for him a lot.
"I think it's sad he's had to be put through what he's been put through, but he's got enough people, I hope, who value what he does and who can see what he does and can field for him."
He went on: "He's a man who has dedicated his life to his country, and changed lives - he's reached the parts that many other organisations can't reach.
"There are so many young people in Britain who will stand up and tell you what he has done for them. That's worth listening to."
In 2011, Charles, then a 72-year-old prince, took Alan on tour of Highgrove House for the BBC, where the pair spoke candidly about gardening.
Last year, the pair came together to discuss their shared love of classical music for a broadcast on Classic FM.
Bear Grylls, Joanna Lumley and Rowan Atkinson
Bear Grylls holds the role of Chief Scout, meaning he has plenty of a connection to the royal family, and he has confirmed he will be at the King's Coronation.
He was also granted an OBE for his services to young people.
Joanna Lumley is also invited, and she recently spoke about her connection with King Charles.
Despite saying they are not "close friends", she said that the King and Camilla have "always been extremely friendly".
Speaking to Metro, she said: "I'm not close friends. The thing is, it's odd this thing about friendship. I think a friend friend, a close friend, is somebody who you can ring up in the middle of the night. I would not know how to get in touch with Prince Charles, let alone ring him at any time."
Rowan Atkinson will be seen on the special day as well.
He was appointed Commander of the Order of the British Empire in the 2013 Birthday Honours for services to drama and charity.
