Rumors about James Hewitt being Prince Harry's father have circulated for decades, following the discovery that the former household cavalry officer had an affair with Princess Diana of Wales, Harry's mother - now, a new play based on interviews may shed some further light into the long-standing controversy.

Although the Royal British Crown and even James Hewitt himself have denied that he is in fact Prince Harry's father, rumors have continued to exist for the past years, particularly considering how much the two men seem to look alike; now, the latest play about Diana's life might help audiences see things more clearly.

According to the United Kingdom edition of The Huffington Post, a writer called Jon Conway is releasing a play entitled "Truth, Lies, Diana," a drama based on both fact and fiction regarding Princess Diana's life and her ultimate death. In the play, it is revealed that the truth about Prince Harry's father might be a bit less clear than what has been said to the public in past years.

It seems that the play aims to "uncover secrets about Diana and her death, that the establishment have tried to keep hidden," according to The Independent, including a shocking revelation about who might be Prince Harry's father - whether it was Prince Charles of James Hewitt; if the latter were proven true, Harry would lose his right to the crown, as he's currently the fourth in line to the throne (soon to be the fifth, after Kate Middleton gives birth to her second child with Prince William next year).

For years, different sources have said that when the Diana and James Hewitt affair began, Prince Harry was already a toddler, which would obviously make it impossible for Hewitt to be the father; however, Metro states that in fact the relationship between them started in 1984, more than a year before the birth of Harry - something that could potentially mean Hewitt is Prince Harry's father.

"Now that doesn't prove that I am his father," says the fictional James Hewitt in the play to a journalist. "It's just the inconvenient truth."
