The royals create a holiday atmosphere.

Kate Middleton hosted the fourth annual “Together for Christmas” service on Friday with her husband Prince William and their three children, sons Prince George, 11, and Prince Louis, 6, and daughter Princess Charlotte, 9.

The couple’s youngest child was photographed holding a red piece of paper with a handwritten note about what he is grateful for.

The family stopped at the famous Kindness Tree outside Westminster Abbey in London to hang their messages on the branches as a dedication to someone who has supported them in their lives.

In honor of the service’s theme of love and empathy, Prince Louis’ note read: “Thank you for grandma and grandpa because they played with me.”

Middleton also penned a letter to the abbey’s 1,600 carol-goers, which include members of the royal family, telling them: “This carol service is a heartfelt celebration for each and every one of you and a reminder that at Christmas and throughout the year about we all have to shine for each other. Because in times of joy and sadness, we are all each other’s light.”

The Prince and Princess of Wales shared footage of their time at the service on social media, captioning the X post: “A wonderful time together with friends, family and those who make a real difference to those around them. “

“This year’s Together at Christmas Carol Service celebrated people who have inspired, counseled, comforted and, most importantly, shown that love is the greatest gift we can receive. Thank you for everything you do!”

Middleton spoke to several volunteers at the event and spent time with her family around the Kindness Tree.

The Princess of Wales is back to her normal duties after spending much of this year behind closed doors following her abdominal surgery in January, cancer diagnosis and subsequent treatment.

In September, Middleton announced that she was now “cancer-free.”

“I can’t tell you what a relief it is to finally have completed my chemotherapy treatment,” she announced in a statement on X.

“My focus now is on doing what I can to stay cancer-free. Although I have completed chemotherapy, my road to healing and full recovery is long and I must continue to take each day as it comes.”

The mother-of-three said she was now looking forward to “getting back to work in the coming months and taking on a few more public engagements when I can.”

Middleton thanked those who supported her during her months-long battle.

“The last nine months have been incredibly hard for us as a family. Life as you know it can change in an instant and we had to find a way to navigate the stormy waters and unknown roads,” she said.

“The cancer journey is complex, frightening and unpredictable for everyone, especially those closest to you. With humility you are also confronted with your own vulnerabilities in a way you have never been before, giving you a new perspective on everything.”

“Despite everything that has happened so far, I enter this new phase of recovery with a renewed sense of hope and appreciation for life,” Middleton added.
