Duchess of Cambridge

Kate appeared alongside the musician Tom Walker in a clip shown at the Westminster Abbey event.

The pair took part in secret filming at a recording studio ahead of the concert, which was broadcast on ITV.

Royal Carols: Together At Christmas was staged for people who supported their communities during the Covid pandemic.

A clip of the duchess performing with Walker on his previously unheard Christmas song, For Those Who Can't Be Here, has been posted on the Kensington Palace Twitter feed.

The court in Nanterre, in the western suburbs of Paris, awarded 100,000 euros in damages to the duchess and her husband, Prince William. It also slapped both the editor of Closer magazine and the chief executive of the publishing group that owns it with the maximum fine possible under French law (45,000 euros or about $53,500).

The couple had asked for 1.5 million euros (nearly $1.8 million) in damages after the magazine and regional newspaper La Provence published grainy photos that showed the duchess sunbathing topless while on holiday in the south of France.

Her appearance marked the first time the 33-year-old Duchess of Cambridge has been seen in public since late July, when she attended the America's Cup World Series in England. It marked her first royal engagement since giving birth to Princess Charlotte, her and William's second child and first daughter, who is now 4 months old. There, she wore her hair in a ponytail.

On Sunday, she wore her long brown hair pinned back, with long bangs framing the sides of her face.
