Kate Middleton shares new family portrait of royal kids in Christmas card

Ahead of the Christmas celebrations, Prince William and Kate Middleton have published the new photos of their children.

The first was them literally being photographed en route to the Queen's Christmas lunch at Buckingham Palace. Those were just car shots, but they gave a clear look at how much Louis has grown in the past couple months.

But the second photo showed the family earlier in a much more casual setting. Air Commodore Dawn McCafferty shared the Christmas card Kate sent her on Twitter. It featured a new family portrait, one where the family posed in matching blue outfits, Elle reports.

The royal kids will spend Christmas this year in Sandringham with the Queen. George and Charlotte are expected to attend Christmas day church service with the royal family for the first time this year. While they've been photographed out with their parents on Christmas day service in Bucklebury—where Kate and William spend Christmas with the Middleton family—they've never been shot alongside the royals in Norfolk.

“It will be so sweet. George and Charlotte will make their Christmas debut, as long as they’re both on good form on the day," a royal source told The Sun, breaking news of the impending milestone. “It’s the picture all royal fans want to see. The royals walking to church on Christmas Day is a rite of passage and so William and Kate didn’t want to expose their children too early, but they feel they’re old enough now."
