But according to one royal biographer, there was only one person who married into the Royal Family who had true "star power." In an interview with People, royal expert and biographer Simon Vigar explained, "[Princess] Diana had a sense of destiny about her. The only aristocrat of the four women [Princess Diana, Queen Camilla, Princess Kate, and Meghan Markle], she knew a lot about it. She would have been a major player in the Royal Family, and it is a crying shame that she's not." But when it comes to the person with the strongest "star power," Vigar believes Princess Diana reigns supreme.
