Video of Prince George chatting with dad Prince William at mom Kate Middleton's garden goes viral

Prince George stealing the show once again!

The cheeky oldest child of Prince William and Kate Middleton visited his mother's brand new garden at the Chelsea Flower Show with the rest of his family over the weekend, and a new clip from their fun day outside shared by the Kensington Royal Instagram account is going viral online.

In the footage, as George swings on the garden's rope swing, Will, 36, asks his 5-year-old son, "What would you give it out of 10, George? How many marks out of 10 would you give it? With 10 being the highest."

"20!" George says excitedly.

"20 out of 10?" William laughs. "That’s pretty good. I think Mummy’s done well!"

"How amazing is that?" Kate, 37, replies as she plays with Louis, 1.

In previous photos shared from the Cambridges' visit to the newly-unveiled garden, George and Charlotte enjoyed swinging on the rope swing, dipping their toes in the stream and running around. Louis, too, ran around the garden with a big smile on his face.

Duchess Kate designed the RHS Back to Nature Garden alongside lauded landscape architects Andrée Davies and Adam White of Davies White Landscape Architects.

"In recent years I have focused much of my work on the early years, and how instrumental they are for outcomes later in life," Kate said in an Instagram caption about the garden. "I believe that spending time outdoors when we are young can play a role in laying the foundations for children to become happy, healthy adults."

"They were throwing stones. I hadn’t actually thought that that was what they would be doing," she added to reporters on Monday. "They kicked their shoes off and wanted to paddle in the stream … using it in a way that I hadn’t anticipated."
