Happy Birthday, Prince George! The little prince that captivated the world last year turns 1 today and Kensington Palace celebrated by releasing a few adorable photos of the heir to the crown.

Earlier this month (July 2), George headed over to the Sensational Butterflies exhibit at London’s Natural History Museum with his parents, the Duke and Duchess of Cambridge and posed for a darling photo shoot with John Stillwell.

In the pics, Kate Middleton and Prince William check out the butterflies and gorgeous flowers with bright smiles on their faces.

“He was fascinated to see them fly but a little scared when they got a bit close to him,” Stillwell told People about prince’s encounter with the Blue Morpho butterfly.

Meanwhile, Kate and Will released a statement to mark their son’s first birthday and said, “We would like to take this opportunity on George’s first birthday to thank everyone over the last year, wherever we have met them, both at home and overseas, for their warm and generous good wishes to George and our family.”
