Coming from George stephanopoulos. Maa picture is worth 1,000 words. This is the first official portrait of will and little prince George since his christening. Hamish Macdonald has the story. Reporter: This is the third official photograph of prince George. It offers an unusually relaxed glimpse of a young family at home in their apartment at kensington palace. 8-month-old George sis on his mother's leave.
