Taylor Swift had allegedly turned down an invitation to perform at King Charles’ Coronation concert back in May.The claims of the pop star turning down the offer come from royal expert Omid Scobie’s new book, Endgame: Inside the Royal Family and the Monarchy’s Fight for Survival. Scobie did not specify any reason as to why the ‘London Boy’ singer had declined the invitation but she did have a show as part of her ‘Eras’ tour the same day as the coronation concert in Nashville, Tennessee.King Charles was crowned as the new monarch on May 6, 2023 which was the day after he took over the title from the late Queen Elizabeth II who died last year.
