Queen Elizabeth once slapped her nephew clean across the fact repeatedly, according to a newly released excerpt from Elton John’s new book “Me“.

While at a party Elton claims the Queen asked her nephew, Viscount Linley, to watch over his sister, Lady Sarah Armstrong-Jones, because she feeling ill and had left the festivities to go rest. Linley disobeyed the Queen and refused to attend to his sister.

“When he [Linley] repeatedly tried to fob her off, the Queen lightly slapped him across the face, saying ‘Don’t’ – slap – ‘argue’ – slap – ‘with’ – slap – ‘me’ – slap – ‘I’ – slap – ‘am’ – slap – ‘THE QUEEN!’”

Pagesix.com reports: Linley then followed the Queen’s instructions.

When the Windsor matriarch noticed John had witnessed her out-of-character behavior, she winked at him and walked away, he writes.

“I know the Queen’s public image isn’t exactly one of wild frivolity, but . . . in private she could be hilarious,” John writes.
