In the upcoming book The King: The Life of Charles III by royal insider Christopher Andersen, it’s revealed that the then-Prince had numerous temper tantrums, including one that was quite smashing.
King Charles III, whom the book — due out Nov. 8 — also reminds us had a massive crush on Barbara Streisand and referred to her as his only pinup, would go into a blind rage often at the expense of just about anyone around him. One such incident involved assaulting his valet after the then-Prince himself lost a cufflink.
