King Charles III and Camilla's reported secret son also mourns after Queen Elizabeth II's passing.

Although King Charles III and Camilla infamously started their love affair while he was married to Princess Diana, they never had a child together. Instead, their share their stepchildren.

However, a man named Simon Dorante-Day claimed that he is the son of His Majesty and Queen Consort. His adoptive grandmother reportedly worked for the Queen in the past.

Before the grandmother's death, she reportedly told him about the secret, telling him that his parents are King Charles and Camilla.

Recently, he also expressed his heartbreak after Queen Elizabeth II's death.

As quoted by Radar Online, the man said his "grandmother" touched everyone before her death.

"Since finding out about the loss of my grandmother Aka Lilibet, I've been inundated with messages of condolence for the loss. Thank you all for your kind words, thoughts, and concern. As many of you have expressed my family and I are mourning not just the loss of Her Majesty but the loss of another opportunity to resolve this issue pleasantly, the right way," he said.

Dorante-Day was born in 1966. It means that King Charles III and Camilla had him before his marriage to Princess Diana - if his claims are true.

However, historians questioned him already as the two did not meet until 1970 - years before his birth. But Dorante-Day insisted that the royal family presented inaccurate dates instead.

Simon Dorante-Day's Tests

Before his recent message, Dorante-Day shared "proof" on Facebook to show that he is indeed a royal-blooded man.

As quoted by GEO, he shared photos taken when he was younger, showing physical similarities and genetic traits to complete the paternity case since the DNA is not available.

He revealed that he also has photographs to support his claims. The alleged love child has also been fighting to get a paternity test while pursuing legal action in the UK and Australia.

This should be taken with a grain of salt as the royal family never addressed his claims nor debunked them.

Prince Charles has two children with the late Princess Diana - Prince William and Prince Harry.

Meanwhile, Camilla has two children from her first marriage to Andrew Parker-Bowles - Tom Parker Bowles and Laura Lopes.
