The Australian man who has been claiming to be Prince Charles and Camilla's "secret son" has reacted to photos that have been circulating online supposedly proving he's related to the royal family.

Scroll on to check out this "proof" for yourselves...

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...

And, according to Charles's authorized biography, their romance rekindled and an affair began in 1986.

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.

Well, until now, that is!

An Australian man came forward back in April boldly 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 has given various interviews 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 claims he 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 on the British morning show, 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.

He even alleged that Princess Diana had some knowledge of his existence.

"I've always been very open to doing interviews and sharing my story because, at the end of the day, I want Charles and Camilla to submit to a DNA test and I believe that making my plight public will help me achieve that," he told 7NEWS.com.au.

Speaking again to 7NEWS, Simon said it is possible that the late princess may have stumbled across evidence that Charles and Camilla had a secret son after the breakdown of her marriage.

"We believe that Diana knew of my existence, that she had put together the pieces," he said. "Diana was at a point where she was finding out answers about her life, how she was wronged – and she was going public with it."

He claimed that one of "Diana's fears was a secret child."

"There were all sorts of rumours flying around, and my existence would've been one of them."

Of course, Simon has been quite causing the stir on social media, with supporters posting photos of him next to the royal couple.

​"And I understand that it's easy to hear my story and think that I'm crazy and making it all up. But I say today what I've said all along - everything I'm claiming is checkable. Everything I'm claiming has been found through public records and reputable sources,"

"There are so many people invested in my story now and helping me, it's really amazing."

"I am a sane and intelligent man, a father and grandfather. I volunteer for the community and worked for many years as an engineer. I know my story is unbelievable, but if you don't believe it - just check it."

And recently, one supporter even said he resembled the Queen herself!

"You have the Queen's eyes. Out of all the pictures and comparisons, you should use this one when anyone ever doubts you," they said.

However, it was a comparison between Queen Elizabeth II and Simon's son Lachlan which had people talking...

"If Queen Elizabeth had short hair it would be hard to say who is who," commented one.

"I must say the resemblance to Queen Elizabeth is undeniable."

And now, Simon himself has reacted to these wild comparisons to Her Majesty The Queen.

Reacting to the photos, Simon told 7NEWS.com.au: "I'm always getting recognized. I got photographed by another passenger on a train last week, on my way to Family Court. He was even videoing me at one point."​

He added:

"I've traveled all around the world and I've always had people stop me and say 'Gee you look familiar' – without being able to put a finger on it. Some used to tell me point blank that I looked like a royal, without knowing my story. It's been a common occurrence throughout my life."

What do you think about Simon's heritage?

Do you believe him when he says he's the son of Prince Charles and Camilla? Or do you think he's simply being delusional?
