Prince William and Kate Middleton just took to social media to share some adorable new photos of their three children.

Entertainment Tonight reported that the new photos were taken earlier this week at Kensington Palace, and they included the legendary Sir David Attenborough with Prince George, Princess Charlotte, and Prince Louis. The images were snapped during an outdoor screening of Attenborough’s upcoming feature film, David Attenborough: A Life On Our Planet.

The caption of the photos explained William and Kate’s friendship with Attenborough.

“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,” it stated. “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,” it added. “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.”

Royal expert Katie Nicholl said that when it came to William’s birthday this year, he and his wife had a “low-key affair.”

“Just on this occasion they celebrated quietly at home,” Nicholl said. “I’m told they got the chance to switch off from their devices. They weren’t actually working yesterday, so it would have been just a nice family day enjoyed with the three of them.”

William and Kate’s three children are growing up right before our eyes. George is 7, Charlotte is 5, and Louis is 2. We can’t wait to see where these three adorable kids go in life!
