Princess Diana had been in a relationship with Dodi Al Fayed when they both died in a fatal car crash in Paris.

On the online forum site Quora, royal fans discussed what would have happened if the couple had a child of their own. After their death, some royal watchers were convinced that Prince William and Prince Harry would have had a relationship with their half-sibling.

Gwendolyn Hendrix McGregor Scherer, a former professor, said that Princess Diana is the mother of all three children. This means that they love the Princess of Wales and would want to make sure that she will be happy no matter what.

Scherer also used Camilla Parker Bowles and Prince Charles’ relationship as an example to answer the question. She said that Prince William and Prince Harry accepted the Duchess of Cornwall in their lives because they knew that she made their dad happy.

If Princess Diana had another child, it is likely that Prince William and Prince Harry would also accept them wholeheartedly.

But Lynne Chamberlain, a former research assistant at the Royal Prince Alfred Hospital, said that it is impossible for Prince William and Prince Harry to have a relationship with their half-sibling. This is because Princess Diana marrying Al Fayed would result in Queen Elizabeth II denying the royal access to her sons’ life.

Chamberlain said that the only time Princess Diana could spend time with her kids (if she were still alive) is if she visited them in England without Al Fayed.

“The reason for this is because of Dodi’s family’s connection to Adnan Khashoggi, a Saudi businessman and arms dealer who was involved in the Iran-Contra Affair,” she said.

Mike McGarity said that if Princess Diana and Al Fayed have a son of their own, Prince William and Prince Harry would have still been civil with each other. They would also be on speaking terms even with Camilla’s children with Andrew Parker Bowles.
