Prince George turns one on Tuesday, July 22, but the first official photo in honor of his birthday has been released now.
British photographer John Stillwell went with the Duke and Duchess of Cambridge to take photos of their son at the Natural History Museum earlier this month. Will and Kate brought George to the "Sensational Butterflies" exhibition where this photo was taken.
Kate is also a Patron of the Natural History Museum.
If you can't get enough of the Royals, there will be two more photos from this photo shoot released before Prince George's actual birthday.
