On Friday, the Prince and Princess of Wales led the Princess' annual Together at Christmas at the Abbey's Lady Chapel.
Kate Middleton and Prince William attended the event along with their three children: Prince George, Princess Charlotte, and Prince Louis.
Several singers contributed to the services including Beverley Knight and Adam Lambert. In addition, musician Jacob Collier and actor Jim Broadbent took part in the event.
The service began with the popular carol, Once In Royal David's City. After that, Beverley Knight and Adam Lambert performed The Christmas Song by Nat King Cole.
Next, Prince William read the passage from the Gospel, before the performance of several songs like Silent Night, Holy Night, and Joy To The World, as well as Hark! The Herald Angels Sing.
The event featured Christmas trees from Windsor Great Park donated by King Charles III, which will be given to local communities after the service.
The event will be aired as part of Royal Carols: Together At Christmas, a special program airing on Christmas Eve, featuring an introduction by the Princess of Wales.
After the conclusion of the event, Prince and Princess of Wales posted on X, saying: "Thank you to everyone who has been a part of our special carol service, Together at Christmas. From the performers whose voices filled Westminster Abbey, to the early years workforce of carers, midwives, nurses and so many more who are not only making a difference to children today but also shaping a happier, healthier world in the future."
