George and Charlotte excitedly arrive at Coronation concert - but Louis is missing

Prince George and Princess Charlotte made their surprise debut at Sunday night’s Coronation concert - earlier than planned, as they were so eager to see the musical acts scheduled to perform.

With a spring in their step and big smiles on their faces, the adorable youngsters arrived alongside King Charles and Queen Camilla, who were also accompanied by Prince William and Kate Middleton.

One notable absence however, was Prince Louis, who was sadly missing from the show, as it was “past his bedtime.” The five year old youngster had already struggled in recent days with the excitement and long hours associated with the Coronation, and even left the ceremony at Westminster Abbey mid-way through on Saturday as it was too much for the little one to handle.

Yet rather than being a last minute decision, Louis' departure had been pre-arranged in advance, with his nanny on hand to help take him home so he could rest and decompress until his balcony appearance later in the day.
