Like all families, the royals have adopted quirky yet fun traditions when it comes to celebrating Christmas.
And it seems that once-close brothers Prince William and Prince Harry were no different and used to share a very competitive but now sadly abandoned tradition every year on Christmas Eve.
The feuding pair used to kick off their festive season at Sandringham with the others royals by taking part in a charity football match with friends and staff from the estate.
William and Harry would usually be on opposing teams for the game, which was played on a pitch opposite the 12th-century home of Tory peer Lord Greville Howard.
The matches over the years saw them battle conditions including heavy wind and rain, with one year William appearing on the pitch in socks from his beloved Aston Villa and Harry being on the end of a tackle that saw him brought to his knees.
However, in 2016 the football tradition came to an end when neither brother turned up for the match - despite both being invited to play in it.
It is believed William missed out as he spent Christmas that year in Berkshire with wife Kate's family alongside Prince George and Princess Charlotte.
Lord Howard said at the time: "They were not expected. One does not like to ask why, but they have enjoyed playing in previous years."
Just hours before the game was due to kick-off, it was revealed that their cousin Zara Tindall had suffered a devastating miscarriage.
Their Christmas Eve football tradition has not restarted since and due to the rift between them, it doesn't look likely to return.
This year, William will be spending Christmas at Sandringham with Kate, George, Charlotte and Prince Louis as King Charles hosts the first festive season of his reign.
Meanwhile, Harry is thought to be spending Christmas with wife Meghan Markle and their children Archie and Lilibet at their home in California.
It is likely to be an emotional time for the royals as they face their first Christmas since the death of the Queen.
Royal Christmases usually feature a morning trip to St Mary Magdalene Church, the greeting of well-wishers, and a family lunch with turkey and all the trimmings.
Charles has pre-recorded his historic, first-ever Christmas Broadcast as monarch, where he will no doubt reflect on the loss of his mother and her legacy.
Traditionally, members of the royal family sit down to watch the televised address when it airs after lunch, usually at 3pm on December 25.
