Prince William, Duchess Kate wear matching jeans in uber-casual Christmas card: See it here

Royals, they're just like us. Or at least they dress like us for their Christmas card.

In perhaps their most casual Christmas photo op yet, Prince William and Princess Kate, both 40, donned regular 'ol jeans and button-downs while posing with their kids: Prince George, 9; Princess Charlotte, 7; and Prince Louis, 4.

The children also kept it casual, each wearing blue shorts. George and Louis donned collared, short-sleeve shirts, while Charlotte wore a light blue blouse.

Each member of the smiling family of five also wore sneakers while walking hand-in-hand down an outdoor path. William and Kate flank their children on both sides in the image.

The couple's annual Christmas card has become a holiday tradition for royal family fans.

Last year's photo showed the prince and the former Kate Middleton sitting side by side, all smiles as their three kids surrounded them. Kate wore an olive green dress that matched her husband's shirt. Prince George was decked out in a camouflage shirt while his younger siblings matched in blue attire.

This year's holiday photo comes less than a week after Netflix dropped the first three episodes of a docuseries centering on Will's brother Harry and his wife Meghan, featuring interviews with the couple, family members and friends. Three final episodes will stream Thursday, part of a multiyear deal between the couple and the streaming platform.

Over the three episodes, which build to the pair's 2018 wedding, the Duke and Duchess of Sussex shared intimate details of their love story, including the moment Harry first laid eyes on Meghan (via Instagram) and details of his proposal. They also addressed the less charming parts of their past, like media harassment and Harry's regret at dressing like a Nazi to a costume party in the mid-2000s.
