And he's off! Little Prince George visited the Natural History Museum in London last month with his parents the Duke and Duchess of Cambridge, to celebrate his first birthday. There will be three photos released to commemorate his big day, and the first picture is here!

Further proof of what dad William said last week (that George will be running faster than he can soon!) the first photo shows baby George walking around the Sensational Butterflies exhibition at the Museum. From BBC's Peter Hunt, the photographer who took the photos for William and Kate, John Stillwell, said that George "was very lively and very sure of himself and confident." He called George a "very determined young boy," a pretty great quality for a future King!

We'll see two more photos on Monday night before George's birthday on Tuesday. Click through the gallery above to see the most adorable photos of Britain's most famous baby!
