Suggesting that things before Diana were more serious than we knew.

But, during the broadcast, many remember Charles being oddly reluctant to say he was in love with Diana.

However, regardless of the tension between the pair, they married on 29th July 1981.

The lavish ceremony was held at St. Paul's Cathedral and was watched by over 750 million people around the world.

Prince Harry was born on 15th September 1984.

Diana threw herself into motherhood.

She had strong ideas about how she wanted her children to be raised, often giving them more freedom than traditional royal heirs.

She was also known for her extensive charity work.

Unlike the other members of the royal family, Diana was determined to use her platform to better the world and dedicated her life to many noble causes, including the land mine crisis.

She also made world news when she shook hands with an AIDS sufferer.

Unlike the typical royal wife, Diana was dead set on doing work for herself and for the betterment of the world, earning her the nickname "The People's Princess."

And the dynamic between Diana and the rest of the royal family was certainly no easier.

Rumors about Queen Elizabeth's distaste for Diana had been rife for years, with sources claiming that she was even "jealous" of the attention Diana drew from the rest of the family.

Allegedly, the Queen wasn't her biggest fan...

And she apparently made no effort to make Diana feel welcome in the family. Andrew Morton, who collaborated with the Princess on the 1992 Diana: Her True Story wrote that “behind the public smiles and glamorous image was a lonely and unhappy young woman" and that she was seen “as an outsider by the Queen."

So, many weren't surprised when the couple officially separated in 1992.

Their divorce was finalized in 1996, though Diana continued with her public appearances and charity work right up until her tragic death in 1997.

But now, over twenty years later...

More unsavory details surrounding her marriage to Prince Charles have emerged.

Simon Dorrante-Day claims he is the secret love-child of Charles and Camilla.

He's said his late grandmother, who used to work for the Queen, told him this many times over his life.

He claims he was born secretly when Charles and Camilla were teenagers.

He claims to have "lots of evidence" about his true parents.

"The documentation that I've got for the adoption is written in my own adopted mother's handwriting," he said.

"So there's lots of bits of evidence like this... that have got to go before the court. It's just unfair that I constantly have to fight this when really, they know the truth."

"My birth certificate is complete rubbish."

​"The longer this thing runs, the more they're going to get egg on their face, not me."

"My grandmother, who had worked for the Queen, told me outright that I was Camilla and Charles' son many times."

Do you believe him? We're pretty skeptical ...
