Andrew Morton spoke about how the Princess of Wales might have related to her daughters-in-law if she had lived long enough to meet them. The royal biographer collaborated with the late Princess Diana on her biography Diana: Her True Story, which was published in 1992.

Meghan Markle would have ‘mesmerised and intimated’ Princess Diana, Morton claims.

But he thinks that if Diana had met her daughter-in-law, the two ladies would have “bonded” over their common experiences.

Mr Morton told the Mirror that he believes Diana would have been pleased by Meghan’s ability to carry herself properly when making public remarks.

The author made the remarks ahead of Diana’s 60th birthday, which would have been on Thursday.

Diana’s sons, Prince William and Prince Harry, will honor Diana’s life and legacy on Thursday by unveiling a monument of her at Kensington Palace.

“She would warm to Catherine, her initial shyness on the public stage reminding her so much of her own early trepidation in front of a screaming crowd,” he said of Diana.

“As for Meghan, she would find the energetic American mesmerising and intimidating.

“Diana was desperate to be known for speeches, rather than fashions, and took lessons to learn how to deliver talks.

“She would have been taken aback on first meeting Meghan, a force of nature able to speak with passion and precision – and all without notes.”

“But as she got to know her and see the vulnerable side of a woman who suffered mental trauma during her first pregnancy – as did Diana – they would have bonded.”

Prince Harry thinks Meghan would have been a good match for his mother.

Diana confessed to having bulimia in her famous BBC interview with Martin Bashir.

In a shocking interview with Oprah Winfrey, Meghan said that she had a mental health crisis while working as a royal.

Meanwhile, Andrew thinks Diana would have been “concerned” about the present schism between her sons William and Harry and would have tried to reconcile them.

He said; “She always saw Harry as the reliable wingman for William, for when he took on the lonely position of Sovereign.

“She may well have approached Charles to work out how to reconcile the two brothers.

“She understood her youngest son, a tendency to wear his heart on his sleeve and his desire to forge his own path.

“After all, she had staged her own great escape and had survived.

“It would be the ultimate irony that the woman who unmasked the inner workings of her marriage and the monarchy would act as peacemaker to save the institution she walked away from.

“One thing is certain though. The boys would have put aside their differences to organise a party to remember for their precious mother.”

Harry is planning to celebrate his mother’s birthday without his wife on Thursday.

“Meghan has just had a baby and has no plans to travel to London for the memorial event planned for the statue unveiling,” an Entertainment Tonight insider said.

Princess Diana died in a vehicle accident in Paris in 1997, at the age of 36, and she never met Meghan, her other daughter-in-law, the Duchess of Cambridge, or her five grandchildren.
