Taylor Swift and King Charles III missed a chance to make friendship bracelets together at his coronation.
Royal watcher Omid Scobie claimed in his latest book, "Endgame: Inside the Royal Family and the Monarchy’s Fight for Survival," that the "Cruel Summer" singer turned down a chance to perform for the king at his coronation ceremony in May.
Swift, 33, already had obligations on her calendar, however, with a string of shows on "The Eras Tour" scheduled at Nissan Stadium in Nashville, Tennessee.

King Charles III and Queen Camilla received a royal welcome to the throne with a star-studded lineup, including Katy Perry, Andrea Bocelli and Lionel Richie, during May's coronation concert.
Multiple reports claimed Harry Styles, Elton John, Robbie Williams and the Spice Girls all declined to perform at the coronation concert on the grounds of Windsor Castle. It was also previously reported that Adele and Ed Sheeran also said no to the historical gig.
Charles, 75, immediately ascended the British throne after his mother, Queen Elizabeth II, died in September 2022. However, his official coronation took place on May 6.
Richie and Perry closed out the show for 20,000 guests at Windsor Castle, where Tom Cruise dropped in with a special video message for the official new king.
