Kate Middleton continues to shine.

To support the grieving Lady Gabriella Windsor, whose husband Thomas Kingston died by suicide earlier this year, the Princess of Wales kindly invited people to help plan her annual carol concert.

Middleton, 42, reached out to Lady Gabriella, 43, over the summer after it was revealed that her husband, whom she married in 2019, had died in Gloucestershire, England, in February. He was 45.

Princess Catherine had asked Lady Gabriella to help select the musical performances for this year’s Together at Christmas extravaganza, hosted by the Princess on December 6 and broadcast on Christmas Eve.

It was reported that Lady Gabriella, the daughter of Prince and Princess Michael of Kent, was touched that the beloved royal had asked her to take part in the planning.

In fact, Gabriella was considered a “true member of the Christmas carol service team” due to her previous experience as a singer-songwriter.

Lady Gabriella “enjoyed her role in the service and was thrilled to be a part of it,” a source told the Daily Mail, while Middleton was “incredibly grateful for her contribution.”

“She was very touched and grateful that the Princess was asked to contribute to her very special concert. She was honored,” the insider added.

Lady Gabriella eventually invited singer Gregory Porter and pianist Rosey Chan to perform at the celebratory concert. A poem was read by Tony winner Sophie Okonedo.

In addition to leading the artist selection process, Lady Gabriella commissioned Restore the Music, a nonprofit organization dedicated to music education for young people.

The jazz ensemble performed as guests entered Westminster Abbey before the service.

Ahead of this year’s event, Princess Catherine – who announced in September that she had completed chemotherapy and is now cancer-free – extended an invitation to people who have made a difference in their communities.

The palace previously said that Middleton wanted to “celebrate the many people who support those in need – people who have inspired, advised, comforted and, above all, shown that love is the greatest gift we can receive.”

It is the fourth time that Princess Catherine has hosted the annual Christmas service, which this year was attended by more than 1,600 invited guests.
