Royal expert Robert Jobson alleges that Katy Perry caused a stir among the royal family when she performed at King Charles III’s coronation in May 2023. Jobson recounts the star-studded Coronation Concert in his upcoming book, "The Windsor Legacy," where Perry and Lionel Richie were the main performers. Perry's demand for special accommodations after learning about Richie's treatment reportedly led to drama, with her entourage partying late into the night and straying into restricted areas. Despite the alleged controversy, Perry expressed gratitude for being an ambassador at the event and later joked about her viral moment during the ceremony. In a Jimmy Kimmel Live! interview, Perry revealed a comical encounter with King Charles and Queen Camilla at Windsor Castle during the coronation.
