During a talk with Australian magazine New Idea, Simon Dorante-Day claimed he was the product of Camilla, 70, and Charles' scandalous affair. He said that while the Duke was still married to Princess Diana, his then-mistress Camilla, 71, got pregnant, but secretly gave birth and gave her child up for adoption before anyone could find out.
"We believe that Diana knew of my existence and that she had put the pieces together," said Simon, 52, adding that Diana was one of the few who knew of his birth, but her tragic death ultimately kept the truth from being exposed.
"At the time, there were all sorts of rumours flying around about the royal family, and my existence was one of them," Simon continued. "I think Diana was at a point where she was finding out answers about her life, how she was wronged, and she was going to go public with it."
Simon was born on April 5, 1966, a few years before Camilla and Charles' affair went public. Though the royal family has not acknowledged his claims or existence, Simon has long said he has evidence that he is, in fact, their love child.
Simon's original birth certificate appears to list fake names for his biological parents, and photos of him from his teenage years show his uncanny resemblance to Camilla's son, Tom Parker Bowles.
Born in England, Simon was adopted by locals Karen and David Day. His adoptive grandparents, Winifred and Ernest, worked for Queen Elizabeth II and Prince Philip at the time, and allegedly told him the secret of his birth.
"I was very close to my grandmother and she told me many times that I was Camilla and Charles' child," Simon said. "She didn't just hint at it, she told me outright."
