November 30, 2019 - 22:35 GMT Emily Nash The Duke and Duchess of Cambridge joined forces with Mary Berry to cook up a festive feast to thank people who will be working on Christmas Day. Prince William and Kate asked the Queen of TV cookery to help them spread seasonal cheer to people connected to their charities who won’t be able to relax with their families over the holiday.
A source told HELLO!:"The Duke and Duchess were joined by Mary on several different engagements over the past couple of months and showed her some of the charities and patronages close to their hearts to explain a bit about why they do what they do. They wanted to show her why they care so much about these organisations and Mary comes up with ideas for recipes for the event.
Viewers will also be taken behind the scenes at the Duchess's visit to RHS Wisley on 10 September, where she talks to Mary about her passion for early years support for children and families and gives her a tour of the play garden inspired by her Back to Nature garden. The two women are seen icing cupcakes for young guests invited to the garden's opening.
