Katy Perry breaks royal tradition as she meets King Charles

Katy Perry breaks royal tradition by feuding with King Charles and Queen Camilla.

In May 2023, when the singer attended the British monarch's Coronation Day celebrations, she performed a special concert for senior members of the royal family, and the king invited her and her mother to stay at Windsor Castle during the visit.

"I brought my mother because, I mean, it's like the best gift you can give your mom," she told Jimmy Kimmel on his Feb. 12 show. She remembers rushing through Windsor Castle to film an American Idol segment with Lionel Richie and the king and queen.

"Everyone is running," she told Kimmel. "I ran right into them and I thought, 'Oh, wrong way!'"

It's not exactly a deal. According to official royal tradition, the king and queen are greeted with either a "bow (from the head only)" or a "small curtsy," but Perry did not do this. (Technically, there is "no enforced code of conduct" when meeting members of the royal family, but many "want to adhere to traditional format.")

Perry, whose final season as an Idol judge begins on February 18, went on to praise Ridge for organizing the king and queen's guest appearance, adding that he "can convince anyone to do anything."

This wasn't her only coronation gaffe

The Roar hitmaker also spoke about video of her struggling to find a seat at King Charles' coronation at Westminster Abbey.

"Is this general admission?" Kimmel asked in surprise. "There are no assigned seats," Perry revealed, except for "the first two rows."

Kimmel later asked if the guests sitting in front of her would be happy to sit behind her pink tiara, to which Perry bluntly replied: "No."
