A man who claims he is Prince Charles and Camilla Parker-Bowles' long-lost son has shared even more "undeniable proof" that he's related to the Royals.
Simon Dorante-Day, 55, who was born in the UK but now lives in Queensland, Australia, has been claiming for years that he is the illegitimate son of the Prince of Wales and Camilla.
In the last few months, Simon has consistently shared photographic "proof" of his royal roots and has even spoken to the media about his outlandish claims.
He says he was conceived in 1966 when Prince Charles was just 17 and Camilla was 18 - long before the future King's eventual marriage to the late Princess Diana in 1981.
Now, the supposed royal has shared another side-by-side photo featuring Prince Charles, Camilla, and himself - all in their younger days - as "evidence" that he shares their DNA.
A number of people took to the comments of the post to agree that there is indeed a resemblance between himself and his apparent parents.
One person wrote: "You look so much like Duchess of Cornwall, and your son got Queen's look and Prince Charles' ears. I pray to God may you find answers to your search as quickly as possible. Every adopted child deserves to know his/her origin. Stay steadfast, friend."
Another agreed: "My goodness, and now I notice Charles' teeth and the extended vertical dimples on your cheeks either side of your mouth, and your bottom lip is suspiciously like Camilla's. And so it goes on..."
While a third added: "You like Camilla. But I seriously doubt you will ever get the DNA test done. The royal family will stonewall and never allow for it to happen. This may change once William is king."
A couple more commenters referred to the resemblance as "undeniable".
Simon previously shared a side-by-side photo of himself when he was a boy along with an image of his alleged grandmother, the Queen who is pictured with Prince Charles.
In another image, he compared a black-and-white photo of the Queen as a young woman with his teenage son Liam.
In February, he posted a snap of himself along with a photo of the late Prince Philip to showcase their purportedly striking similarities.
In an interview with 7NEWS.com.au, Simon said he often comes across new comparison photos that "stop me in my tracks, even to this day."
He told the outlet: "All the royal fans and supporters who send them to me, they’re amazing. And I really think it’s like an Agatha Christie novel for them, where they’re looking for clues and searching for answers."
The British-born Aussie continued: "There are so many people invested in my story now and helping me, it’s really amazing. But at the end of the day, it would be really nice to wake up in the morning and not have to look for evidence and keep defending it."
Simon was adopted by a family from Portsmouth, England - who he says had links to the Royal Family. He was supposedly informed by his adoptive grandmother that he was Prince Charles' son.
