There were several key takeaways from Kate Middleton’s Christmas carol concert, including Prince George and Prince Louis’s resemblance to their dad, Prince William, and Princess Catherine’s super-telling body language.

While at the “Together at Christmas” celebration at Westminster Abbey on Dec. 6, Princess Kate revealed why she was so proud of her 6-year-old son, Prince Louis. Kate attended the annual holiday celebration alongside her husband, Prince William, and their three children: Louis, Princess Charlotte and Prince George.

Princess Kate spearheaded the Together at Christmas carol service with The Royal Foundation in 2021 as a way to thank those who gave back to their communities during the COVID pandemic, and it's continued as a tradition ever since, becoming a staple on the royals' annual calendar.
