Her Royal Highness has organised her customary festive musical service at Westminster Abbey, with attendees featuring members of the royal family, famous faces, and community champions who have made a difference in their neighbourhoods.
The 1,600 guests will enjoy a mix of traditional hymns, orchestral pieces, and literary excerpts from performers including Chiwetel Ejiofor and Kate Winslet.
The theme of the concert, held in the glowing Westminster Abbey on the afternoon, is generosity and expressing affection towards one's neighbour.
Among the guests will be Jonathan and Anna Cordiner, whose young girl was lost to a brain tumour, and who established a foundation, a charity called Kayleigh's Wee Stars, to support families who have a child with a terminal illness.
"Your efforts, love, and understanding, often without fanfare or recognition, and without any hope for reward or acknowledgement, make an extraordinary difference to the lives of others," wrote Catherine in a letter ahead of the festive gathering.
The Princess of Wales is continuing her own measured re-emergence to public life following her health challenges and treatment, last month delivering her initial major address in two years, in which she reflected on recognising the "quiet, often invisible work of caring".
Attendees entering the Abbey can listen to budding artists supported by the Future Talent organisation, co-founded by the Duchess of Kent to broaden opportunities for instrumental training.
Carys Wood, aged 18, who is a trumpet player and is from southwest Wales, has been helped by the trust, with grants helping towards equipment, teaching, and travel fees - and she said it was "incredible" to be taking part in tonight's service.
"Musical pursuits are frequently pricey," Carys said. She is now studying at the Royal Academy of Music, and added that "everyone should have the opportunity" to cultivate their performance abilities.
Eliza, Carys's sister who is 11, who plays the euphonium, will also be at the Abbey. "I never imagined I would perform in front of so many notable figures," she said.
Attending the service will be individuals spanning multiple eras.
That will include nine-year-old Saphia Turner, winner of a youth community award, who sells artwork and carries out sponsored challenges to generate funds for local food charities.
The Abbey has been adorned with specially made wreaths, with well-known chef Mary Berry and flower expert Simon Lycett assisting in their creation.
Taking to the stage will be Katie Melua, the Westminster Abbey choristers and a Cornish sea shanty group, the Fisherman's Friends, who said the invitation to sing was "a dream come true."
This annual carol service will be broadcast on ITV1 on Christmas Eve.
