Prince William's new documentary shows previously unseen photos of Prince George, Princess Charlotte and Prince Louis

Much to the delight of royal fans, Prince William has shared three never-before-seen pictures of his children in his new ITV conservation documentary Prince William: A Planet For Us All.

As part of the documentary, the Duke of Cambridge was followed by cameras for two years as he embarked on a global mission to help stop climate change.

And Prince George, seven, Princess Charlotte, five, and Prince Louis, two, also appeared during the documentary via the three new photographs.

In the first image, Prince Louis could be seen playing in the sand with a bright blue bucket.

Meanwhile, his older brother was pictured helping in the garden, as he dug a hole in some soil with a spade.

In the final image, Princess Charlotte, dressed in navy wellingtons and a check skirt, could be seen planting a flower.

During the documentary, William also shared some fun facts about his two older children.

Filmed visiting a group of children who had built a huge bug hotel that they called "Bugingham Palace," the father-of-three was asked: "Is Princess Charlotte cheekier than Prince George?"

To which he replied: "No, they’re about as cheeky as each other. They’re very cheeky!"

Elsewhere in the documentary, William also joked Charlotte is "trouble".

Introduced to three-year-old Pacha during a 2018 visit to Tanzania, he told the youngster: "You look like trouble, you're just like my little Charlotte."

Too cute!
