Kate Middleton, Prince William and kids casually pose on a motorcycle for their 2019 Christmas card

Christmas time for the Cambridges!

Although the photo has not *officially* been released by the palace, one lucky recipient has shared a sneak peek of Kate Middleton and Prince William's family holiday card! Of course, the snapshot includes Prince George, Prince Louis and Princess Charlotte, but it's a stark difference from last year's family photo!

In a now-deleted tweet, Air Commodore Dawn McCafferty shared the sweet and casual family shot to Twitter, with all five posing on a motorcycle and sidecar for the photo. "Wishing you a very Happy Christmas and New Year," the card reads, followed by the Duchess of Cambridge's signature. Reporter Benjamin Wareing later shared a close up of the shot to his followers.

The photo shows the Cambridges still color-coordinating, but very casual in what looks like a beach shot. Kate wore a sold-out dress from Boden for the occasion.

Last year's holiday photo was taken by photographer Matt Porteous at the couple's Anmer Hall country home in Norfolk, England, with the crew matching in jeans and sitting on a tree trunk. And their 2017 photo was much more formal. Captured by Chris Jackson, it shows the then family-of-four in color-coordinated outfits, standing for the camera.

The family kicked off their Christmas celebrations on Wednesday and joined Queen Elizabeth at her annual holiday lunch at Buckingham Palace.

Prince William arrived separately with Prince George, while the Duchess of Cambridge (in festive Emilia Wickstead!) arrived with her two youngest children in-tow.

Photographers even got a rare glimpse of the adorable Prince Louis in the back of his mother's car as the duchess arrived on the palace grounds. The royal, who will turn two in April, was most recently spotted at the crown's Trooping the Colour celebrations this summer, where he made his big balcony debut!
