Kate Middleton and Prince William have released pictures and video footage of Princes George and Louis and Princess Charlotte playing in the Duchess' Chelsea Flower Show garden, and it's just adorable.
The Cambridge kids appeared in the rare family pics which show Prince Louis running through the garden, which Kate co-designed.
The royal children spent almost an hour on Sunday playing in the Back To Nature Garden, which aims to encourage children to spend more time outdoors. Kensington Palace shared six photos and a video of their weekend adventures, writing in the captions: "Over the past months, Prince George, Princess Charlotte and Prince Louis have helped The Duchess gather moss, leaves and twigs to help decorate @The_RHS Back to Nature Garden.
"Hazel sticks collected by the family were also used to make the garden’s den."
So, can we officially declare Prince Louis the world's cutest baby?
Adventurous George and Charlotte can be seen dangling their legs over the stream, while Louis toddles off with a stick. If you look closely, you might spot George climbing across the river in the background of his brother's shot.
As well as having plenty for the children to enjoy, the garden pays tribute to Princess Diana with her favourite flowers: forget-me-nots.
The duchess told the BBC: "I really hope that this woodland that we have created really inspires families, kids and communities to get outside, enjoy nature and the outdoors, and spend quality time together."
