Prince Louis – the youngest child of Prince William and Kate Middleton – had a memorable moment during the Trooping the Colour ceremony.

Louis, 4, waved to the crowd, made funny faces and covered his hears during the noisy flypast as the family stood on the balcony of Buckingham Palace.

An image of Louis covering his ears and yelling next to Queen Elizabeth has taken off on social media, quickly becoming a meme.
