Tom Cruise has been confirmed as one of the stars to appear at the Coronation Concert on 7 May.
The event, to crown the new King and Queen Consort, will take place in the grounds of Windsor Castle to round off the weekend’s proceedings and is expected to be attended by 20,000 people.
Cruise, Winnie the Pooh and Dame Joan Collins will appear in a series of pre-recorded sketches revealing little-known facts about the King.
The Top Gun star has enjoyed a long-standing relationship with the Royal Family, having taken part in last year’s Platinum Jubilee celebrations, and has been frequently seen with the Prince and Princess of Wales.
The inclusion of beloved literary figure Winnie the Pooh suggests that there might be a moment of magic to match the late Queen sharing tea with Paddington Bear at the Platinum Party At The Palace.
Other stars confirmed to appear include singer Sir Tom Jones, adventurer Bear Grylls and former Strictly Come Dancing professional Oti Mabuse.
Music will come from act such as Paloma Faith, Olly Murs, veteran rock guitarist Steve Winwood, Nicole Scherzinger of The Pussycat Dolls and Chinese pianist Lang Lang.
Bollywood star Sonam Kapoor will deliver a spoken-word performance.
Take That, Katy Perry and Lionel Richie will also perform at the event, which will be broadcast on BBC TV and radio, as well as classical acts including Andrea Bocelli and Welsh bass-baritone Sir Bryn Terfel.
Winwood will sing alongside the Commonwealth virtual choir, featuring choirs and individuals from more 40 Commonwealth countries.
The 74-year-old said: “I was alive and just about remember the coronation of Her Majesty Queen Elizabeth II and I, together with millions and millions of other people all around the globe, am a lifelong monarchist.
“So to be included in the coronation celebrations of King Charles and Queen Camilla is for me a lifetime achievement for which I’m extremely humbled and honoured.”
Bollywood actress Kapoor will also join the choir. She said: “I am honoured to join the Commonwealth virtual choir, celebrating His Majesty’s love for music and art.
“It’s a momentous occasion that signifies a commitment to a positive, inclusive, and optimistic future for the United Kingdom, with the choir’s music paying tribute to the royal legacy and promoting unity, peace, and joy.”
TV presenter and singer Murs added: “It’s such an honour to be asked to perform at such an iconic castle.
“An event that will go down in history, and one I’ll be proud to tell my kids about one day.”
