Christopher Andersen Says Prince William Temper Terrifies King Charles
Christopher Andersen’s prince william temper claims put Prince William at the center of a new royal book rollout. The royal author said William has “great bellowing tantrums” and that King Charles is “terrified” when they happen. Andersen made the comments in an interview with Page Six ahead of his new book launch.
Andersen said William is usually “kind and considerate to a fault” with staff and members of the public, but alleged that those habits change with Charles. A former royal staff member also said William raises his voice at his father when frustrated, adding that William has a huge, booming voice.
Christopher Andersen on William
Andersen said William has “great bellowing tantrums” and that Charles is “terrified” by them. He said William is always “kind and considerate to a fault” with staff and members of the public, drawing a sharp line between how William behaves in public and how he allegedly behaves in private with Charles.
The account comes from Andersen’s new book, Kate! The Courage, Grace, and Power of the Woman Who Will Be Queen, and from his interview ahead of its launch. The story rests on allegations from a royal author and a former royal staff member, not on public comment from Prince William or King Charles.
Charles and the royal staff account
The former royal staff member said, “When he gets frustrated, he does resort to shouting [at Charles].” The same source said, “William has a huge, booming voice” and added, “Much louder than his father’s, so it’s not something you soon forget.”
Andersen also described Charles as having a “Vesuvius temper,” linking William’s alleged outbursts to a father-son relationship that already carries its own volatility in his account. In his 2022 biography, Andersen said Charles tore a sink off the wall after losing a cufflink down the drain, an anecdote he used to portray the monarch’s own temper.
Kate! and the book rollout
The new allegations arrived as Andersen promoted Kate! The Courage, Grace, and Power of the Woman Who Will Be Queen. For readers following royal reporting, the immediate takeaway is not a palace statement but a contested portrait built from Andersen’s interview and a former staff member’s recollection.
That leaves the book itself as the next point of interest: Andersen’s claims are now attached to a public launch, with the discussion centered on William’s reported outbursts, Charles’s reaction, and how much weight readers give to an author’s account of private royal behavior.
