Princess Charlotte was keeping her big brother Prince George in line as the Platinum Jubilee celebrations came to an end Sunday.
During a special moment that represented the future of the monarchy, Queen Elizabeth stood on the balcony of Buckingham Palace alongside Prince Charles, Camilla, Duchess of Cornwall, Prince William, Kate Middleton and their children, George, 8, Charlotte, 7, and Prince Louis, 4.
As the national anthem, “God Save the Queen,” played, George was spotted placing his hand on the balcony ledge. Charlotte then sweetly nudged her brother’s arm, telling him to fix his posture. George quickly corrects himself by standing up straight and putting his arms by his side. (Watch the sweet moment play out in the video above!)
