Kate Middleton shared new photos of herself preparing for the upcoming royal Christmas Eve special, "Together at Christmas."

Middleton, 39, was photographed adding red ribbons to a Christmas tree and hanging a festive wreath while wearing a Christmas sweater to match the occasion.

"I'm so excited to be hosting #TogetheratChristmas here at @wabbey, a place that's really special to William and me," she captioned the new photos.

"We wanted to say a huge thank you to all those amazing people out there who have supported their communities," she added. "We also wanted to recognise those whose struggles perhaps have been less visible too."

The special will be broadcast on Christmas Eve.

The "Together At Christmas" carol special was filmed on Dec. 8. Middleton wore a bright red dress for the evening.

"What a special evening, seeing so many familiar faces, as well as meeting inspirational people who have gone the extra mile for their community in recent times," a statement from the Duke and Duchess of Cambridge said at the time.

The carol special was attended by the U.K.'s "unsung heroes."
