KING Charles and Queen Camilla cracked jokes with Lionel Richie and Katy Perry while making a surprise appearance on American Idol.
The newly crowned royals joked with the iconic music stars as they spoke virtually to the US talent show’s host Ryan Seacrest after the coronation concert.
Lionel said: “Now we are trying to figure out what we can do to bring something different to the show.
“So,… I have a surprise.”
Charles, wearing a blue suit, and Camilla, wearing a long blue jacket, then walked out and joined them, with a shocked Katy saying: “Oh goodness.”
“I just wanted to check how long you will be using this room for,” King Charles said laughing.
Smiling broadly, Lionel replied: “We have to give up the room up right away.”
While Katy joked with Queen Camilla: “Are we making too much noise?”
The Sun understands that this was a genuinely spontaneous meeting decided by the King and Queen during the evening.
And it was reflective of a long-standing warm relationship between the royals and the two top singers.
King Charles also praised the singers for their performances at the star-studded concert in the grounds of Windsor Castle.
Lionel Richie sang his much-loved All Night Long as Charles and the Royals danced.
Katy Perry performed her hit Roar as Princess Charlotte sang along with mum Kate.
The monarch said: “No, thank you for your brilliant performance and thank Katy as well. It really was.”
Camilla said of their performance: “Fantastic, absolutely fantastic.”
King Charles said it was “great to have you both here.”
“I understand there is a party,” Lionel said.
“Ah you have heard about that,” King Charles joked back.
Lionel replied: “Well, you are throwing a party right next door.”
King Charles smiled back: “Had we better take you to the party but you’re busy with all these other things.”
“As soon as we finish, we are coming to the party,” Lionel replied enthusiastically.
As Charles and Camilla walked off, Richie added: “We love you guys, and congratulations.”
With the country continuing to celebrate Charles, 74, yesterday’s one-off show saw the royals on their feet as they boogied to Katy Perry, Lionel Richie and Take That.
The two-hour spectacular featured music from the likes of Paloma Faith, appearances from Piers Brosnan and Tom cruise and a heartfelt speech from Prince William.
Brit favourite Take That concluded the concert with a special feature from singer Calum Scott.
The King was on his feet waving a Union Jack as he danced along to the song Shine.
Last night’s blockbuster event saw Prince William deliver a speech paying tribute to the late Queen.
Wills said she’s “keeping an eye on us” as he thanked Charles.
The Prince of Wales, 40, stepped onto the Union Flag stage decked out in red, white and blue at Windsor Castle to huge cheers.
He told how coronations are a “declaration of our hopes for the future”.
Speaking just over 24 hours after swearing allegiance to the new King, the heir to the throne described the Royal Family’s collective pride in his “Pa”.
