Zara and Mike Tindall showed solidarity with the Prince and Princess of Wales as they joined other members of the Royal Family for a Christmas concert at Westminster Abbey.
The pair were pictured arriving at the service, with Zara wearing a dress and a coat and Mike, who recently took part in reality show I'm a Celebrity, donning a blue suit for the occasion.
Royals put on a united front at the event just hours after the final part of the Sussexes' documentary dropped on Netflix.
The ceremony was also attended by the King and Queen Consort, as well as Prince George and Princess Charlotte.
The Countess of Wessex, the Duke and Duchess of Gloucester, the Duke of Kent and Princess Alexandra were also there.
Princess Beatrice and her husband Edoardo Mapelli Mozzi, Princess Eugenie and Jack Brooksbank, Prince and Princess Michael of Kent, Lady Gabriella Kingston also attended.
Lord and Lady Frederick Windsor, Thomas Kingston, and Daniel and Lady Sarah Chatto were also among the guests.
More than 1,800 people are gathering in the abbey for the concert, staged to recognise the "selfless efforts of individuals, families and communities across the UK, and celebrate and showcase the joy that human connection and togetherness can bring".
Kensington Palace said the second carol service Kate has held is dedicated to the late Queen and the values she demonstrated throughout her life, including "duty, empathy, faith, service, kindness, compassion and support for others".
The palace said these principles are "shared and personified by the inspirational guests who have been invited to the abbey in recognition of their tireless work to help and care for those around them".
A Christmas tree in the abbey is decorated with small Paddington Bear decorations, a nod to the late Queen's famous sketch, while guests were greeted with atmospheric snowflakes from a snow machine as they arrived at the entrance.
The palace tweeted pictures of the decorations and said: "Getting ready to welcome our #TogetherAtChristmas guests, celebrating those who have gone above and beyond in their communities and paying tribute to Her Late Majesty The Queen."
