Prince George, Princess Charlotte and Prince Louis joined their grandfather King Charles and Queen Camilla as they attended the royal family's traditional Christmas Day church service.
The royal children, who were accompanied by the Prince and Princess of Wales, walked the short distance from Sandringham House to St Mary Magdalene Church, but it was little Louis and his cousin Mia Tindall who really stole the show.
The young royals smiled at members of the public who had gathered to catch a glimpse of the royal family as they walked to the morning church service. The outing marks Louis' second time when he has joined his eldest siblings for the annual walkabout.

On the latest episode of HELLO!'s A Right Royal Podcast, HELLO!'s Royal Editor Emily Nash touched upon the royal family's Christmas at Sandringham. "The visit to Sandringham is a set piece, and that has been going for such a long time now," she explained.
"They've been going to Sandringham since the eighties. We now have come to expect the little walk from the 'big house' - as they call it - down to St. Mary Magdalene church on Christmas Day.
"Of course, for a lot of the royals that's actually their second church service of the day. Some of the eager beavers are down there for the early morning one, but it's the second service - the 11am one -where people come along to stand outside and wish members of the royal family a happy Christmas."
Of the royal children's appearances in recent years, Emily added: "We've seen the children getting involved in the last few years, which is lovely. It's now as much a part of Christmas Day as the King's speech is."
The royals are residing at their private Norfolk estate, where the late Queen Elizabeth II traditionally hosted her family over the festive period. The royal tradition began in 1988 when Windsor Castle was being rewired, and one of the highlights has always been the Christmas Day walkabout before the church service.
