Elton John is a longtime friend of the royal family and hes certainly seen some things including a particularly hilarious incident involving Queen Elizabeth II.

In an excerpt from his upcoming memoir Me published in the Daily Mail last week, John wrote about a funny royal moment in which the British monarch playfully slapped her disobeying nephew.

I know the Queens public image isnt exactly one of wild frivolity, but I think thats more to do with the nature of her job: she cant exactly sit there cracking jokes during the State Opening of Parliament, the pop star wrote. But in private, she could be hilarious.

He continued:

At another party, I saw her approach Viscount Linley and ask him to look in on his sister, whod been taken ill and had retired to her room.

When he repeatedly tried to fob her off, the Queen lightly slapped him across the face, saying Dont SLAP argue SLAP with SLAP me SLAP I SLAP am SLAP THE QUEEN!

When the queen saw John starting, he wrote, Her Majesty gave me a wink and walked off.

Talk about slapstick comedy.
