Here It Is: Prince George's Official 1st Birthday Photo

In case you don't have it marked on your calendar, the royal baby turns a year old on Tuesday—and to mark the occasion, three days in advance, his royal parents have released an official photo of Prince George, taken 20 days in advance. Prince William, wife Kate, and the babe headed to a butterfly exhibit at London's Natural History Museum on July 2 to take the photo, which shows the heir to the throne walking toward photographer John Stillwell of the UK's Press Association wire service. "He's quick on his feet," Stillwell tells People. "I was kneeling down to take the picture and he was on top of me as soon as he started walking." (More Prince George of Cambridge stories.)
