Prince Harry has taken a swipe at his brother's hair loss in the latest blow from his explosive memoir.
The jibe at the Prince of Wales' baldness is just one of many shocking claims he's put into Spare, which is due to hit shelves in the UK on Monday.
The book however has accidentally gone on sale days early in Spain, with several other bombshells dropped including an alleged assault on Harry from his brother in a fight over Meghan, and claims that he killed 25 Taliban fighters while deployed in Afghanistan.
But the hits at his brother, who he has revealed he calls 'Willy', have also extended to his appearance after he brought up his waning head of hair.
In the book, Harry mentions seeing William at his grandfather Prince Phillip's funeral in April 2021, noticing his diminished resemblance to their mother, Princess Diana.
“I looked at Willy, really looked at him, perhaps for the first time since we were little," Harry writes, bringing up his "familiar scowl".
He describes his bother's thinning hair as "alarming", noting it was "more advanced than mine" despite only being two years his junior.
It's one of many devastating blows for the royal family, who have so far declined to comment on any of the allegations made.
Royal insiders however have told The Mirror that Harry would likely "never be forgiven" for some of the damaging claims and details of private conversations.
A source described some of the words in Spare as "vicious and targeted", adding there would "never be a way back for Harry".
They said: "I don’t doubt he still loves his father and his brother but it’s impossible to see how he won’t come to bitterly regret his decision to do this.
“He knows he will be labelled a traitor, by crossing a red line so many times, his father, his brother, the Princess (of Wales) and Camilla, it’s utterly extraordinary.”
Other wild claims made by the Prince include that he took cocaine when he was 17 and lost his virginity to an "older woman" in a field outside a pub.
Spare is set to hit UK book shops from Tuesday following tight pre-launch security measures to ensure its revelations would not be leaked beforehand.
