An Australian man made headlines last week when he came forward claiming to be the secret son of Prince Charles and Camilla...
And now, he is adamant about having "proof" of his royal heritage.
Here's the full story...
Now, rumors surrounding the true extent of Charles and Camilla's relationship have been rife for decades.
The couple first met in 1970 at a Polo match at Windsor Castle and quickly hit it off.
They dated for around a year, however, after Charles left to go overseas with the Royal Navy, Camilla reconnected with her former partner, Andrew Parker Bowles, and they got engaged.
Camilla went on to marry Parker Bowles in 1973...
And Charles married Lady Diana Spencer 7 years on in 1980.
However, despite their separation, Charles and Camilla remained firm friends.
In 1995, just before their divorce, Princess Diana gave that BBC Panorama interview where she revealed she had known about her husband's affair with Camilla.
"Well, there were 3 of us in this marriage, so it was a bit crowded," Princess Diana famously said of Camilla's role in their lives.
So people were hardly surprised when, a year on from Diana's tragic death, Charles began the process of legitimizing his and Camilla's relationship.
In 1998, Charles confirmed a report in a British tabloid that Camilla had met Prince William, with the papers speculating that she would soon be meeting Prince Harry, too.
And the rest is history.
Despite a frosty start with the Queen, who allegedly disapproved of a divorcee entering the family, Camilla became a solid part of the monarchy and married Charles in a civil ceremony in 2005, thirty-five years after their friendship initially blossomed.
Since then, Charles and Camilla have enjoyed a happy and drama-free marriage in the public eye.
But this week, that is all set to change.
As stated earlier, an Australian man has come forward claiming to be the secret love child of Charles and Camilla.
Fifty-five-year-old Simon Charles Dorante-Day is convinced that the Duke and Duchess of Cornwall are his biological parents, and appeared on the British morning show, This Morning, to provide "proof" that he is at the center of a far-fetched cover-up.
Of course, people don't quite know what to make of his wild claims...

Simon, pictured as a young man below, was conceived in 1965 when Charles was just seventeen and Camilla was eighteen.
Despite this being 5 years before the royal couple is understood to have met, Simon, who is a father-of-9, claims Camilla fell pregnant and kept it a secret.
"My grandmother, who had worked for the Queen, told me outright that I was Camilla and Charles' son many times," he had originally told 7 News.
"We owe it to our children for them to have answers... At the end of the day, I'm just a man who's looking for his biological parents - and every road takes me to Charles and Camilla."
He even claimed to have met Camilla several times as a child.
As a young boy growing up in Hampshire, Simon says he was taken to a number of impressive homes to meet his biological mother.
"I remember going to this house on top of the hill, and I was taken to the front door and my adoptive mother knocked on the front door – she never went in, I just went in."
But, speaking to Phillip and Holly on This Morning, he recalled his adopted mom and grandmother saying that the "visitations needed to stop."
"I was walking to my nan's [house] when I was about 5 or 6 and I heard nan say to mom, 'Well, the visitations have got to stop, he's going to remember them.' I walked in the door and said, 'Remember what?' and of course I copped a mouthful for talking out of turn."
And as for any evidence to back up his claims?
Well, he insists that he underwent a procedure when he was 8 years old to change his eye color from blue to brown in an attempt to make him look less regal.
"I don't think that they had any choice but to do that," he said. "But it was because of the gossip in Portsmouth around the time. In those times, blue and blue made blue. There was never any inquisition about that."
"My oncologist will tell you that one of my lenses is perfectly round and one of them is oval-shaped like a football - a rugby football. This is why I have a vision problem."
Of course, the legitimacy of this "proof" is questionable, with Phillip pointing out that Holly's blue eyes don't make her related to the Queen.

Buckingham Palace are yet to comment on the allegations made.
