Prince George is on the move!

Just before his first birthday on July 22, the Duke and Duchess of Cambridge have released a picture showing the royal baby walking toward the camera. 

The proud parents chose a butterfly exhibit at London's Natural History Museum as the location for this photo, released in honor of their son's big milestone. 

In the pic, George is wearing striped overalls and a blue polo shirt, and he looks determined to walk across the pebbled ground.

While the little one is one of the world's most famous babies, the royal couple has said that George has had a "normal upbringing."

Writer Katie Nicholl, who wrote a feature story about Prince William and Kate Middleton for their family cover issue of Vanity Fair, said, "they take George to playdates at the homes of friends."

We can't wait to see how the royals celebrate George's big day!
