The Duke was visiting Esplanade Park’s Christmas market in Helsinki, Finland, on the second day of his Finland tour, when he came across the big man himself.
He was pictured joking around with Santa as he handed over his son’s list.
Close-up photos of Prince George’s list not only revealed what he wanted for Christmas, but also gave us a sneak preview of his adorable handwriting.
Half-way down the list the four-year-old - who has been “nice” this year - had written that he wanted a “police car”.
Prince George also signed off the list with his name.
Have your kids written their lists to Santa yet?
