The young royal, 10, accompanied his father, Prince William, 41, to watch the final of the world s oldest club tournament and present the FA Cup to winners Manchester United.
Not seen in public since Christmas Day, the Princess of Wales will be disappointed to be absent from St David s Day celebrations this year. But Wales is a land close to her heart.
Despite her well mannered public appearances, Princess Charlotte has also delighted royal fans with her childlike ease in front of the cameras, pulling faces and talking to photographers.
William and Kate will journey the length of Wales on Tuesday, first visiting Holyhead in Anglesey, North Wales, and then travelling to Swansea in South West Wales.
