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.

Catherine has cut several inches off her perfectly-styled chestnut locks, for a shoulder-brushing style.

Much like her outfit choices, which fly off shelves as soon as the designers' details become known, the new "Kate" is likely to be a hit with fashionistas.

She debuted the look with a teal tailored skirt suit by British designer LK Bennett at a London charity event with husband Prince William on Wednesday.

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.
