Some royal fans believe that Princess Diana and Prince Charles may have had a secret daughter through IVF.

On the online forum site Quora, some royal fans speculated on the possibility of the former royal couple having a third child. Jade Worthington, a professional social worker, came up with an entire story of how Princess Diana and Prince Charles would’ve planned to have another baby.

“Of course, two unhappily married people never have a higher priority than finding a surrogate to gestate and give birth to a secret third heir to the throne, using their gametes, before they divorce, because the mother is too photographed to hide a pregnancy,” she wrote.

Worthington went on to say that the most important thing is to keep the identity of Princess Diana and Prince Charles’ daughter a secret so whoever she is must have been deprived of what Prince William and Prince Harry have been entitled to all their lives.

Chealyn Callura, who works for Tumblr, said that she also thinks Princess Diana and Prince Charles have a secret daughter. However, more people said that it seems impossible for Princess Diana and Prince Charles to have another baby and then keep them secret from the entire world.

“They had two sons, what on earth would make you think they needed IVF and why would they keep a daughter secret? I think maybe you read too many of those scandal rags,” Laura Warwick Martin, a former fundraiser, said.

Gina Seldarius, a part-time watcher of the royals, said that there is no reason for a high-profile couple who has been blessed with two children to suddenly have problems conceiving a third child if they really wanted to have one.

Seldarius added that it is difficult to hide Princess Diana’s pregnancy if that was the case because she was always visible in public even after her divorce from Prince Charles.
