The details, both good and bad, of Princess Diana's doomed relationship with Prince Charles have been plastered on tabloids and gossip publications for years.
One particular rumor involves Prince Harry's paternity.
According to Celebrity Dirty Laundry, the prince's stepmother, Camilla Parker Bowles, is convinced that her husband's second son isn't his biological offspring.
She reportedly demanded Prince Harry undergo a paternity test to prove that he was the product of Princess Diana's flings.
Former military man, James Hewitt, is allegedly the 31-year-old royal's real father, not Prince Charles. He supposedly met Lady Diana 18 months before Prince Harry was born.
He was recently caught trying to sell of the love letters written by the charitable princess to him during their affair. Furthermore, they share shockingly similar features.
The gossip magazine further pointed out that the Duchess is pushing to ruin her husband's ex-wife's saintly image by proving that Prince Harry was somebody else's son.
Prince William and his wife, Kate Middleton, are reportedly not having any of the drama however. CDL further reported that the Duke and Duchess of Cambridge are teaming up to defend their little brother from their step-mother.
"The Duke and Duchess of Cambridge have already planned to fight back, saving Princess Diana's secrets and outshining the love letter scandal," the article read.
This came after news that Prince Harry defended his sister-in-law against the Duchess of Cornwall's "verbal assaults."
"[Kate's] more regal than YOU'LL ever be!" he allegedly screamed at his step-mother during a fight.
Bowles promptly replied, "Get off your high horse - you're not even a real royal! You're the product of one of your mother's flings!"
It looks like the siblings have each other's backs. CDL further noted that the Cambridges are planning to uphold Princess Diana's memory by going to the Taj Mahal, to recreate "lonely pilgrimage to the tomb."
"It seems innocent enough, but Kate and William are making a point to visit the very bench Princess Diana once sat on for a photo that became an iconic image of her isolation and marriage troubles. There, the Duke and Duchess plan to honor Diana's memory," the article further shared.
