Prince William Sickened By Prince Harry’s Plan to Work on Princess Diana Doc: ‘A Slap in the Face’

The bad blood between Prince William and Prince Harry shows no end in sight — and their most recent rift involves their late mother, Princess Diana.

According to source, William, 43, is none-too-pleased about Harry, 40, and wife Meghan Markle reportedly working with Netflix on a documentary about the late royal, who tragically died at the age of 36 years old in 1997.

“As everyone knows he hates Netflix with a passion, just like all the royals do back in England because of The Crown and the way they were portrayed on the show,” the source explains to Examiner. “The show completely trashed their grandfather and essentially accused him of being a cheating dog, and it gave a very nasty portrayal of their father too.”

The historical drama, which spans six seasons, follows the royal family, and the rise and reign of the late Queen Elizabeth II.

“It sickens William that his own brother would work with them at all,” the source continues, “let alone on something related to their beloved mother.”

According to the source, there’s absolutely no chance Harry is under the illusion that William would be fine with the streaming giant releasing a project involving Lady Di.

“[Harry] knows exactly how his brother feels about Netflix, so the fact that he’s going ahead with this is such a slap in the face,” explains the source. “It’s like nothing is sacred with him when it comes to the almighty American dollar.”

Though there’s been rampant speculation that Harry is on his way to reconciling with his estranged father, King Charles III, there’s likely no chance for the brothers to make amends anytime soon — especially now.

“If there was even a sliver of hope for reconciliation after these peace talks, this has just totally blown that,” says the source.

Now, the dad of three — who shares Prince George, 12, Prince Charlotte, 10, and Prince Louis, 7, with wife Princess Kate — is ready to wage war over protecting Diana’s legacy.

“It’s unlikely William can stop this legally, but make no mistake he’s going to try,” adds the source. “He won’t let Harry get away with this without a fight.”
