Cheeky Prince Louis follows King Charles' lead to wave at the crowd

Royal fans have reacted to Prince Louis' antics during the Royal Air Force flypast over Buckingham Palace yesterday. On June 14, the country came together to mark King Charles's official birthday, accompanied by a spectacular display of military pomp and pageantry. The Royal Family then waved to crowds from the balcony of Buckingham Palace as part of an annual tradition. Prince William and Kate Middleton's youngest child, Louis, put on perhaps his most animated display yet.
