Royal biographer Catherine Mayer says King Charles was once accidentally headbutted by an ex-girlfriend while she was following strict royal-style protocols. Speaking while promoting her book “Divide & Rule,” Mayer describes a behind-the-scenes encounter in which the ex-girlfriend, reportedly observing two rules or procedures, moved in a way that led to contact with Charles. The accounts presented by outlets repeat Mayer’s characterization of the incident as accidental rather than intentional, and they frame it as part of the broader theme of how royals conduct day-to-day interactions.
Both reports attribute the story to Mayer and present it as an anecdote shared publicly in the context of her media work for the book. While the coverage focuses on the “headbutted” description and the claim of “strict protocol,” neither source provides additional corroborating details such as dates, location, or the identity of the ex-girlfriend. The reporting therefore centers on Mayer’s recollection rather than new, externally verified information.
