The British Royal family has released a photo of toddler Prince George ahead of his first birthday.

The photo shows the young prince walking with his arms up during a visit to the "Sensational Butterflies" exhibit at London's Natural History Museum on July 2.

The photo was released on Saturday in a tweet from Clarence House.

Two more photos will be released on Monday ahead of Prince George’s birthday.

Prince George is third in line for the British throne, behind his grandfather, Prince Charles, and his father, Prince William, the Duke of Cambridge.

The toddler will turn 1 on July 22.
