Queen Elizabeth has often been reported to have a cheeky sense of humor that might seem surprising coming from the UK’s longest-ruling monarch. However, what may be more surprising is that she also isn’t afraid to throw her weight around when it comes to the powerful title she holds.

In Elton John’s new book (via Express UK), he recalled a time he attended a party with the royal family and witnessed Her Majesty shutting down her nephew, Viscount Linley when he objected to following a direct order she had given. The Queen asked her nephew to check on his sister, who had fallen ill and gone to her room, but he declined so as not to miss the party. However, John recalled that the Queen refused to let it go and made it clear to her nephew who was in charge.

“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!’” he wrote.

The encounter reportedly not only worked to set her nephew straight but also led to the Queen giving the famous singer a wink after realizing he had witnessed the whole thing.

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

More recently, the Queen’s sense of humor seemed to come through in a resurfaced clip from the documentary “The Queen at 90,” which aired on ITV at the time.

In the documentary, the Queen is seen walking with then Prime Minister David Cameron after inviting him to her Scottish estate at Balmoral, and as the two wandered around the estate, different elements of the Queen’s décor were spotted.

Among the items was a cheeky pillow on one of her couches, which featured the words “It’s good to be Queen” on them.
