Sir Elton John has paid tribute to Diana, Princess of Wales, on the 25th anniversary of her death, saying: “You will always be missed.” The 75-year-old veteran musician, who was close friends with the princess, shared a photo on Instagram of them laughing together to commemorate the occasion. Diana, the mother of Prince William and Prince Harry, was 36 when she was killed in a car crash in Paris on August 31 1997.
