The Duchess of Cornwall revealed she had more in common with singer Lady Gaga than meets the eye at the Royal Variety Performance.
Meeting the singer before the show at the Hammersmith Apollo, London, Camilla told the 'Born This Way' singer: "My grandchildren call me Gaga".
Accompanied by her husband the Prince of Wales, the Duchess also met singer Robbie Williams and charity bosses before the show.
Camilla, wearing a red lace dress, was given flowers by the young granddaughter of Bill Kenwright, producer of the performance, before the royal couple took their seats.
Host and comedian David Walliams led a group of people to the royal box, asking Charles and Camilla "can I see your tickets please?", before joking to the group: "There's some riff-raff here sitting in your seats."
Gaga and Williams performed in the show alongside Sting and Emeli Sande.
The Prince appeared as a special guest at the Royal Variety during a magic trick performed by Britain's Got Talent winner Lance Corporal Richard Jones.
He wrote a two-digit number on a piece of paper, screwed it up and threw it into the audience.
With the help of the band of the Household Cavalry and an audience member, L/Cpl Jones revealed he knew the number - and had in fact predicted it at the start of the show.
He then told the story of his older brother, a member of the British bomb disposal team, using playing cards.
L/Cpl Jones's brother, who had worked in Helmand Province in Afghanistan, then arrived on stage with members of his team.
The poignant performance earned L/Cpl Jones a standing ovation from the audience and the royal couple.
