Wait, are Kate Middleton and Mary Berry teaming up?

This is everything.

Kate Middleton is one of the most talked-about women in the world, making news for everything from her royal fashion sense to her sweet family moments with her husband Prince William and three children, Prince George, Princess Charlotte and Prince Louis.

It was a collaboration that made the Duchess of Cambridge headline news this week however, as the 37-year-old teamed up with baking icon and national treasure, Mary Berry.

Yes, this is not a drill.

Kate Middleton and Mary Berry surprised guests together at Woking's Back to Nature festival at RHS Wisley, opening the new site that is said to be inspired by the Back to Nature garden Kate designed for the Chelsea Flower Show earlier this year.

Unfortunately there was no baking involved, but Kate and Mary spent time with the children at the opening, shared jokes together and even went on a joint ride of the grounds in a tractor-pulled trailer.

'Today The Duchess of Cambridge opened the #BacktoNature play garden at @RHSWisley and attended the Back to Nature festival with @The_RHS Ambassador Mary Berry, which celebrates the value of communities to our wellbeing and marks the culmination of the RHS garden project,' read the caption to a sweet Instagram snap of Kate and Mary on the Kensington Royal page. 'The Back to Nature play garden was inspired by The Duchess’s designs and includes elements such as the hollow log from the #RHSChelsea Flower Show garden, and the wildflower meadow and rolling hill showcased at #RHSHampton.

'Her Royal Highness has spent much of the last eight years meeting charities and organisations who work every day to make our families and communities stronger. The Duchess took the opportunity to invite many of them to the "Back to Nature" Festival to celebrate their contribution to society and to further highlight the importance of those involved in the Early Years sector coming together to support a fundamental change in how society approaches childhood development.'

Wisley's Back to Nature Garden Festival is taking place until September 15
