She may be one of the most famous faces in the world, but the Queen can sometimes get away without being recognised.
Her former protection officer Richard Griffin has revealed how the monarch once encountered a group of Americans while dressed in a headscarf and tweeds while out walking near Balmoral, according to the diary section of The Times.
“Have you ever met the Queen?” they asked.
“No,” she replied, then pointed at her policeman and quipped: “But he has.”
The Queen traditionally spends her summer break at her Balmoral estate in Aberdeenshire – her private home which was handed down to her through generations of royals.
She is apparently never happier than when she is at Balmoral, where the royals gather for family barbecues.
Prime Minister David Cameron once said there was not much “chillaxing” – chilling out and relaxing – at Balmoral, with the royals spending their time riding, fishing or walking.
The Queen also once met a shopper in Sandringham in Norfolk who did not recognise her and declared that she looked just like the Queen.
“How very reassuring,” the monarch is said to have remarked.
