Here's why Prince William was told off by the Queen at the Trooping of the Colour ceremony

Britain's Prince William was told off by Queen Elizabeth at the Trooping the Colour ceremony.

The 33-year-old royal was scolded by his grandmother at this year's annual event on Saturday, when he knelt down to talk to his two-year-old son Prince George whilst they made their appearance as a family on the balcony of Buckingham Palace, London, according to Hello! magazine.

The 90-year-old monarch's gesture, which saw Her Majesty nudge the Duke of Cambridge in the arm before gesturing for him to stand up, was captured when her Birthday Parade was aired.

The father-of-two - who has George and 13-month-old daughter Princess Charlotte with his wife Duchess Catherine - swiftly stood up, whilst his younger brother Prince Harry, 31, appeared to let out a little chuckle at his misfortune.

However, Harry was scolded for finding the telling off amusing.

Meanwhile, the Duke of Cambridge has admitted he received a "b******ing" from the Queen for his mischievous ways when he was younger.

Speaking previously about his childhood, he said: "[Peter Phillips and I] were chasing Zara around who was on a go-cart, and [we] managed to herd Zara into a lamppost and the lamppost came down and nearly squashed her.

"And I remember my grandmother being the first person out at Balmoral to come running across the lawn in her kilt. She came charging over and gave us the most almighty b******ing, and that sort of stuck in my mind from that moment on."
