{{#rendered}} {{/rendered}}Prince Harry's new memoir divulges family secrets as well as addresses rumors that have plagued the British royal family for some time.
In his book, "Spare," Harry tackles the long-running joke that he is not the biological son of King Charles III.
"'Who knows if I'm really the Prince of Wales? Who knows if I'm even your real father? Maybe your real father is in Broadmoor, darling boy,'" Harry writes his father would joke, per NBC News.

Although the Duke of Sussex writes that his father would "laugh and laugh" at the rumors, Harry found it to be "a remarkably unfunny joke, given the rumor circulating just then that my actual father was one of Mummy's former lovers: Major James Hewitt."

"One cause of this rumor was Major Hewitt's flaming ginger hair, but another cause was sadism," Harry writes. "Tabloid readers were delighted by the idea that the younger child of Prince Charles wasn't the child of Prince Charles. They couldn't get enough of this 'joke,' for some reason. Maybe it made them feel better about their lives that a young prince's life was laughable."
{{#rendered}} {{/rendered}}Prince Harry clarified any confusion, definitively explaining, "Never mind that my mother didn't meet Major Hewitt until long after I was born, the story was simply too good to drop."

In 2002, during an interview with the Sunday Mirror, Hewitt himself refuted claims he was Harry's father.
{{#rendered}} {{/rendered}}"There really is no possibility whatsoever that I am Harry's father. I can absolutely assure you that I am not," he said at the time.
"Admittedly the red hair is similar to mine and people say we look alike. I have never encouraged these comparisons and although I was with Diana for a long time I must state once and for all that I'm not Harry's father. When I first met Diana, Harry was already a toddler," he noted.
