Prince Louis is talking and it sounds like his delicious first words were just scrummy.

Kate Middleton revealed on the new BBC holiday special, A Berry Royal Christmas, which airs Monday and also stars Prince William and former Great British Bake Off judge Mary Berry that the 19-month-old toddler likes to talk about the beloved cooking show personality.

One of Louis first words was Mary, because right at his height are all my cooking books in the kitchen bookshelf, Kate said, according to the BBC .

And children are really fascinated by faces, and your faces are all over your cooking books and he would say Thats Mary Berry, the duchess said. Louis would definitely recognize you if he saw you today.

In the special, Berry accompanied the royal couple on visits to various charities and patronages, and helped throw a party to thank those who work and volunteer during the holiday season.

Kate and Berry attended an event together in September at the Royal Horticultural Societys garden in Woking, though it wasnt known then that two were working on a TV special.
