Princess Diana's royal biographer shared a couple of thoughts on what the late royal would've thought of her daughters-in-law, Meghan Markle and Kate Middleton.

Talking about Queen Elizabeth II's decision, Daniela Elser, a royal commentator wrote in the New Zealand Herald, "While Harry and Meghan still very much retained their titles, the loss of their ability to use their HRH would surely have carried a particular sting."

Royal experts suggest that Prince Charles and Princess Diana's marriage would have worked if they waited a little longer.

Prince Charles once requested Princess Diana to act like Sarah Ferguson who was always jolly.
