With just a matter of days to go before the sparkling display of pomp and pageantry of King Charles' Coronation, further additions to the party have been revealed, with some very unlikely stars set to join the line-up.
Tom Cruise, Winnie the Pooh and Dame Joan Collins will feature during the Coronation Concert celebrating the crowning of the King and Queen Consort.
Alongside Sir Tom Jones, adventurer Bear Grylls and former Strictly Come Dancing professional Oti Mabuse, they will appear in a series of pre-recorded sketches revealing little known facts about the monarch.
Music acts Paloma Faith, Olly Murs, veteran rock guitarist Steve Winwood, Pussycat Dolls’ Nicole Scherzinger and Chinese pianist Lang Lang have also been added to the line-up.
Among the other new names set to perform are Nigerian singer Tiwa Savage, DJ Pete Tong with his Ibiza Classics project, and winner of The Piano TV talent show, Lucy.
Bollywood star Sonam Kapoor will also deliver a spoken-word performance.
While the late Queen's eldest son officially became Monarch the moment she passed away at 3.10pm on September 8 last year, the Coronation will celebrate the beginning of his reign. His wife Queen Camilla will also be crowned.
The event at Westminster Abbey will be filled with royal tradition, with both Charles and Camilla wearing priceless crowns covered in jewels worth millions of pounds.
Members of the Royal Family, including the Prince and Princess of Wales and Prince George, are set to have starring roles.
On the Sunday night of the Bank Holiday weekend, King Charles is putting on a huge Coronation Concert at Windsor Castle.
However, it's been reported that putting together the line-up hasn't been too easy.
A number of big names have reportedly turned down invitations to join, including Sir Elton John and the Spice Girls among the list of those who can't make it. Harry Styles, Ed Sheeran, Adele and Robbie Williams are all said to have said no due to their jam-packed schedules.
However there are still countless big names who could make the list – so it will definitely be a night to remember.
For the Coronation itself, Charles has commissioned 12 new pieces of music. There are six orchestral pieces, five choral and one organ commission. The job of creating the pieces has been given to world-renowned British composers including Andrew Lloyd Webber, Patrick Doyle and Iain Farrington.
Other stars to be announced join the line-up of Take That, Katy Perry and Lionel Richie, plus classical acts including Andrea Bocelli and Welsh bass-baritone Sir Bryn Terfel.
The event on May 7 in the grounds of Windsor Castle will be in front of a crowd of 20,000 members of the public and invited guests and will be broadcast across BBC television and radio stations.
The concert will be broadcast on BBC One and iPlayer, as well as BBC Radio 2 and BBC Sounds.
