The Duke and Duchess of Cambridge were in Sandringham spending the holidays with Queen Elizabeth II. Prince William and Middleton were photographed joining the monarch, Prince Charles, Camilla Parker Bowles attending the morning church service. Their children Prince George and Princess Charlotte also joined them for their traditional Christmas walk.

Kate also had a short conversation with Karen Anvil and her daughter Rachel where the duchess shared her one regret on that day.

"Kate was talking to my daughter about clothes and how she was feeling too hot. She said: 'I really shouldn't have worn this,'" Anvil told Metro.

Prince Harry and Meghan Markle were missing from the church service as they were spending Christmas and New Year in Canada. Several royal fans criticized the Duke and Duchess of Sussex for their decision.
