A Berry Royal Christmas: What To Expect

Kensington Palace shared to social media some behind the scenes images as well as gave fans some insight into what we can expect during the special. We surely can expect the Duchess to be icing some cakes with Berry while they chat about Kate's commitment to youth, we can expect them to visit Action on Addiction, and The Passage Charity to learn more about homelessness prevention, among many other exciting things.
