Prince William opened up on the Apple Fitness+ podcast ‘Time to Walk’ about what happens behind closed doors at the royal family’s annual Christmas morning church service at St. Mary Magdalene on the grounds of the Sandringham estate.

Kate Middleton delighted onlookers, joining other members of the British Royal Family for the annual Christmas morning walk to and from their church service at Sandringham, in Norfolk. Kate was accompanied by her husband Prince William and their three children, George, Charlotte and Louis, as they joined King Charles and Queen Camilla.

The royal family gathered at Sandringham to celebrate the holiday, even as Prince Harry and Prince Andrew sat out the festivities.
