Prince Harry's car has already been seen leaving London, as he appears to have snubbed the invtiation to lunch with his father, the newly crowned King Charles, and the rest of the Royal Family.
Harry was seen smiling as he departed Westminster Abbey in a black car, with the same car later spotted being escorted out of the capital by a police motorcade, seemingly heading towards Heathrow Airport.
While it hasn't been confirmed that the Duke of Sussex will be flying back to the US immediately following the ceremony, it's certainly a possibility that he will be jetting back as soon as possible to celebrate his son Prince Archie's birthday.
Harry is thought to have been invited to a lunch at Buckingham Palace, which is being held following the coronation ceremony.
