Prince George speaks in public for the FIRST TIME in new adorable family video

He may be five-years-old, but we have NEVER heard Prince George talk.

Until now ...

Amongst the excitement of the newly-released photos of the Duke and Duchess of Sussex's wedding photos and pictures of the Duke and Duchess of Cambridge's three children exploring their mother's RHS 'Back to Nature' Garden at the Chelsea Flower Show, Kensington Palace have now released the most adorable new video of George talking to his doting father.

While playing in Kate Middleton's garden display with his sister Princess Charlotte, 4, and one-year-old brother, Prince Louis, the young royal takes centre stage as Prince William asks him to rate his mum's garden design out of ten.

The future king can be heard sweetly replying: "Twenty out of ten."

"That's pretty good, I think mummy's done well," William said.

"Wow, how amazing is that?" Kate said delightedly as she watched over Prince Louis.

According to Kensington Palace, over the past months, Prince George, Princess Charlotte and Prince Louis have "helped The Duchess gather moss, leaves and twigs to help decorate" the garden.

They added: "Hazel sticks collected by the family were also used to make the garden’s den."

The Duchess told the BBC in her first solo television interview: "I really feel that nature and being interactive outdoors has huge benefits on our physical and mental wellbeing, particularly for young children.

"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."

The 'Back to Nature' Garden was designed in cooperation with award-winning landscape architects Andrée Davies and Adam White.

The world-famous show will be officially opened on Tuesday.
