Prince William may look calm and polished in public, but behind closed palace doors, insiders claim the future king has a fiery temper that can shake the royal family to its core.
According to royal author Christopher Andersen, Prince William has been known to unleash loud, explosive outbursts during tense confrontations with his father, King Charles III — and the shouting matches are reportedly intense enough to leave the monarch rattled.
“William is capable of great bellowing tantrums,” Andersen revealed while discussing his new book, “Kate! The Courage, Grace, and Power of the Woman Who Will Be Queen.”
The royal expert claimed that while William is typically respectful and gentle with palace staff, strangers, and especially his wife Kate Middleton and their children, things reportedly change when emotions boil over inside the royal family.
A former Highgrove staffer allegedly told Andersen that William’s booming voice is impossible to ignore during arguments with Charles.
“When he gets frustrated, he does resort to shouting,” the staffer claimed. “William has a huge, booming voice. Much louder than his father’s, so it’s not something you soon forget.”
The claims are adding even more fuel to long-running rumors of deep tension inside the monarchy — particularly between William and his younger brother, Prince Harry.
In Harry’s explosive memoir “Spare,” the Duke of Sussex accused William of physically attacking him during a heated argument over Meghan Markle. Harry claimed his older brother became “piping hot” before grabbing him by the collar and throwing him to the floor, where he landed on a dog bowl that shattered beneath him.
The shocking allegation stunned royal watchers when the book was released and painted a much darker picture of the brothers’ relationship than the palace had ever publicly acknowledged.
But Andersen says William’s temper may run in the family.
The author previously claimed King Charles himself has what he described as a “Vesuvius temper.” In an earlier book, Andersen alleged that Charles once ripped a sink off the wall after losing a cufflink down a drain during a fit of frustration.
Royal fans also got a rare public glimpse of Charles’ anger shortly after Queen Elizabeth II’s death in 2022, when cameras caught the king furiously complaining about a leaking pen during a signing ceremony.
“Can’t bear this bloody thing,” Charles snapped at the time while wiping ink from his hands. “Every stinking time.”
Despite the latest claims swirling around the palace, Buckingham Palace has not publicly commented on the allegations involving William’s temper.
Still, the reports are likely to reignite questions about what life inside the royal family is really like once the cameras stop rolling.
He better be careful what he says and does. At this rate, he will not be the one who sits on the throne.
