The Cambridge kids met "Planet Earth" narrator and famous environmentalist David Attenborough, and their reactions were captured on camera.

Prince William, Kate Middleton, and their three children — Prince George, 7; Princess Charlotte, 5; and Prince Louis, 2; met Attenborough in the gardens outside Kensington Palace.

The Duke and Duchess of Cambridge shared photos of the meeting on their official Instagram page on Saturday, saying that Attenborough visited the palace earlier in the week. In the photo of the family with Attenborough, Princess Charlotte appears to have her hands on her face in excitement over meeting the conservationist.

The Duke and Duchess of Cambridge are delighted to share new photographs of their family with @DavidAttenborough. The photographs were taken earlier this week in the gardens of Kensington Palace, after The Duke and Sir David attended an outdoor screening of Sir David’s upcoming feature film ️ ‘David Attenborough: A Life On Our Planet’. With a shared passion for protecting the natural world, they continue to support one another in their missions to tackle some of the biggest environmental challenges our planet faces. This includes working together on The @EarthshotPrize the most prestigious global environment prize in history – further details of which will be shared in the coming weeks. When they met, Sir David gave Prince George a tooth from a giant shark the scientific name of which is carcharocles megalodon (‘big tooth’). Sir David found the tooth on a family holiday to Malta in the late 1960s, embedded in the island’s soft yellow limestone which was laid down during the Miocene period some 23 million years ago. Carcharocles is believed to have grown to 15 metres in length, which is about twice the length of the Great White, the largest shark alive today.

Prince William and Middleton also announced that they are working with Attenborough on the Earthshot Prize, a project the couple launched in late 2019. The cash prize is awarded to five people each year who can solve environmental problems.

Prince William and Middleton shared a clip of the Earthshot Prize launch video — which is narrated by Attenborough — on Instagram in December 2019.

"Led by Prince William and a global alliance, the Earthshot Prize will inspire the planet's greatest problem solvers to solve Earth's greatest problems: the emergencies facing our natural world," the caption read.
