Estelle, 2, was filmed decorating a Christmas tree with her parents, Crown Princess Victoria and Prince Daniel. When asked what Father Christmas says, Estelle replies "Hoho, there are good children here" giving her mother a laugh as the toddler jumbles up the words.
Traditionally in Sweden Santa Claus asks on his arrival if there are any good children present before handing out the gifts – if they've been well-behaved of course.
Estelle, who was born on February 23rd 2012, has hogged the headlines in the past when she put in a star performance at her aunt Madeleine's wedding when she tried to grab her mother when she was delivering a speech.
Estelle is second in line to the Swedish throne after her mother.
