He might well be the future King of England, but Prince William can still expect a right royal telling off from his grandmother when he needs it. The Duke of Cambridge was standing on the balcony of Buckingham Palace alongside the Queen, his wife Kate Middleton and the couple's two children as they watched the RAF air display in honour of the Queen's 90th birthday.

But as the 33-year-old knelt down beside Prince George he was promptly reprimanded by his grandmother, who tapped on his shoulder and appears to say "Stand up William". Looking somewhat sheepish, William does as he's told after the public ticking off, which unfortunately for William, was caught on video.

The Queen was joined by her entire family for the annual Trooping the Colour ceremony and the Red Arrows fly-past, with Princess Charlotte making her debut on the balcony.

Speaking in the documentary The Queen at 90, the Duke revealed that while he has as a teenager sometimes fallen foul of his grandmother for his high jinx, he shares a very close bond with her.

"She's been a very strong female influence and having lost my mother at a young age, it's been particularly important to me that I've had somebody like the Queen to look up to.

"[She's someone] who's been there and who has understood some of the more, um, complex issues when you lose a loved one," he explained. "So she's been incredibly supportive and I've really appreciated her guidance."

Meanwhile, the hilarious gif has been doing the rounds on social media.
