The Princess of Wales is hosting her annual Christmas carol concert at Westminster Abbey, with guests including royals, celebrities and local heroes who have helped their communities.
The 1,600 guests will hear a mix of carols, music and readings from actors such as Kate Winslet and Chiwetel Ejiofor.
The theme of the service, held in the candle-lit Abbey on Friday afternoon, is kindness and showing love to others.
Among the guests will be Anna and Jonathan Cordiner, whose daughter died of a brain tumour, and who set up a charity, Kayleigh's Wee Stars, to support families who have a child with a terminal illness.
Prince William, and the couple's children George, Charlotte and Louis, were greeted by Catherine outside the Abbey ahead of the service.
