How Did Prince William, Kate Middleton React To Prince Harry's Memoir 'Spare'?

Prince William and Kate Middleton are not thrilled by the claims that have emerged from Prince Harry's upcoming memoir, "Spare," according to reports.

Days before its release, extracts from the Duke of Sussex's book were leaked to the press, revealing awkward moments and shocking encounters involving the Prince and Princess of Wales.

Prince Harry's revelations, which included claims of a physical altercation with his older brother, left Prince William and his wife both feeling "very upset" and "hit them very hard," an unnamed insider told Us Weekly.

"They're both confiding in each other right now," the source claimed.

The future king and queen consort would have rather "handled these issues behind closed doors" and "wished Harry wasn't so public and cutting" with his allegations against his family, the insider added.

Vanity Fair royal correspondent and editor Katie Nicholl, citing unnamed royal sources, also told Page Six that Prince William is "privately seething and devastated by what Harry has done. And just cannot forgive Harry for the things that he's written."

The "New Royals: Queen Elizabeth's Legacy and the Future of the Crown" author went on to claim that the royal family had been "bracing themselves for something raw, something explosive" but were not actually ready for the claims Harry made about them.

She suggested that Prince Harry's actions don't appear to be in line with his claims that he wants to reconcile with his father King Charles and brother Prince William.

"They've been taken aback by the level of detail and just how far Harry has gone in all of this," Nicholl claimed. "To paint such an unflattering picture of the royal family and a very unsavory side of his brother and an uncaring side of his father... It just does not appear to be the actions of a man trying to reconcile with his estranged family. It really feels like a line has been crossed."

In an extract from the book obtained by The Guardian, Prince Harry claimed that Prince William once physically attacked him during an argument over Harry's wife, Meghan Markle. He alleged that his older brother grabbed him by the collar and knocked him to the floor, leaving him with a visible back injury.

Prince Harry also took a jab at Prince William's hair loss, calling it "alarming."

Elsewhere in his book, the Duke of Sussex detailed an "awkward moment" between his wife and his sister-in-law in 2018. He claimed that when his wife asked to borrow the Princess of Wales' lip gloss when she forgot hers, Middleton "reluctantly" gave it to the former "Suits" star and "grimaced" when Markle squeezed some onto her finger and applied it to her lips.

"Spare" will hit shelves Tuesday.
