My grandchildren call me Gaga, Camilla tells singer
The Duchess of Cornwall has told Lady Gaga how they share names as they met before the Royal Variety Performance.
As they were introduced, Camilla told the Bad Romance singer: "My grandchildren call me Gaga."
The US pop star shook hands and chatted with the duchess and the Prince of Wales as they met a host of stars including Robbie Williams, Barry Gibb and David Walliams before the show at London's Hammersmith Apollo.
Famed for her outrageous fashion sense, on the night Gaga opted for a glamorous ball gown that appeared muted next to Williams's sequinned dinner jacket.
Charles shared a joke with the Take That star and appeared to tip him off that his bow tie was askew.
Williams and bandmate Gary Barlow were among a stellar line-up performing at the annual event that in recent years has included the winner of ITV talent show Britain's Got Talent.
This year it was the turn of magician and soldier Richard Jones who amazed the audience with Charles as his able assistant.
For one trick he guessed a number the prince had written on a piece of paper and tossed into the crowd.
After telling a moving story about his brother, a member of the British Army's bomb disposal squad, L/Cpl Jones received a standing ovation from the audience and the royal couple.
Speaking during rehearsals for the big night, the 26-year-old told the Press Association: "It's a really exciting performance, telling a really poignant story which is really important to my family in particular, but it should also touch the hearts of many people watching around the country."
Walliams hosted the show and ended the night dressed as an ostrich alongside entertainer Bernie Clifton.
At one point in the show, 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."
The show also featured Walliams singing Something Stupid with Williams - a song the former member of Take That released with Nicole Kidman.
Amber Riley, known for her role in American series Glee, wowed the audience with her rendition of And I Am Telling You, while Sting performed his hit Every Breath You Take.
The Royal Variety Performance will be broadcast on ITV next Tuesday.
