Like any family, the royals love continuing their long-established traditions on Christmas - a black-tie dinner, Gran giving a speech to the entire country, y'know, the usual.
But there's one tradition that Prince Harry won't be taking part in this year - the traditional Boxing Day bird shoot on the Queen's Sandringham estate in Norfolk.
Harry will miss out on the spree as he's keen not to upset his fiancée Meghan Markle, an animal rights activist who often eats vegan. Wonder whether the royals will still be eating turkey this year.
Instead Prince Charles and Prince William will take part in the shoot without Harry - presumably while he and Meghan do something that doesn't involve killing pheasants, partridges or ducks.
"The Boxing Day shoot was always going to be a tricky issue," a royal insider told the Sun. "Meghan is a keen animal rights campaigner and doesn't like hunting in any form.
"Harry loves it and has always been out there on Boxing Day. But if it means breaking with long-standing royal traditions to avoid upsetting her, so be it."
It's going to be a weird Christmas for the Windsors this year as Meghan will break royal tradition by being the first unmarried partner to spend Christmas Day with the family.
Historically, royal couples have had to be married before they could be together for the festivities - even Prince Will and Kate Middleton had to spend Christmas apart in 2010.
But the Queen is said to have made an exception for Harry's American bride-to-be as the pair's wedding is only five months away. That's a pretty quick turnaround.
The pair are set to get married on 19 May 2018 - which also happens to be the day of the FA Cup Final. If the BBC coverage gets shafted for the royal wedding, footy fans are going to be fuming.
Harry and Meghan are set to arrive in Norfolk today and will stay with Prince William and his wife Kate at Anmer Hall near to Sandringham. The Queen took a train up to King's Lynn on Thursday.
The former Suits star Markle's given up a lot to be with Harry, leaving her home in Toronto to move in with Harry at Nottingham Cottage on the grounds of Kensington Palace.
She even had to leave her dog Bogart behind as the labrador-shepherd cross was deemed too old to make the journey to the UK.
Ah well. Maybe she and Harry can hang out with the Queen's corgis while Her Maj and Prince Philip watch Charles and William shoot some things.
