Catherine reveals Prince Louis' first word - and it was inspired by Mary Berry!

It seems Mary Berry may have found her youngest fan – in little Prince Louis!

The Duchess and Duke of Cambridge have just taken part in A Berry Royal Christmas, co-hosted by TV chef Mary, and shared a few insights into family life with the Cambridges.

As well as revealing that William is a dab hand in the kitchen, Catherine delighted viewers - and Mary Berry herself - by telling them what Prince Louis’ first ever word was. And it’s not what you may expect!

Catherine commented while chatting to the former GBBO host, "One of Louis' first words was 'Mary' because right at his height are all my cooking books in the kitchen bookshelf.

“And children are really fascinated by faces, and your faces are all over your cooking books and he would say 'That's Mary Berry.’”

The Duchess of Cambridge also told co-host Mary Berry that Prince Louis would, “definitely recognise you if he saw you today”.

Prince William also opened up about his children – and how his late mother, Princess Diana, influenced his and Catherine’s parenting style of Prince Louis, Prince George and Princess Charlotte.

"She realised that it was very important when you grow up – especially in the life that we grew up – that you realise that life happens beyond palace walls, and that you see real people struggling with real issues," he said, discussing how he speaks to his children about homelessness.

"She liked to challenge the social norms about charities and about disadvantages and vulnerable people."

"I know it sounds a little bit contrite – but on the school run already, bear in mind six and four (George and Charlotte's age), whenever we see someone who is sleeping rough on the street I talk about it and I point it out and I explain.

"And they are all very interested. They are like: 'Why can't they go home?'"

A Berry Royal Christmas aired on Monday 16 December at 8.30pm on BBC One.
