Kate Middleton honored the late Princess Diana by wearing her favorite pearl earrings for the National Service of Remembrance on Sunday.

The Princess of Wales stepped out in the Collingwood-designed jewelry at the annual event to honor British and Commonwealth servicemen who died in war.

She was photographed on a balcony at The Cenotaph in London, wearing a brimmed hat and an all-black outfit with three poppy pins to commemorate fallen soldiers.

Middleton, 44, is assumed to wear the pins in honor of her great-grandmother’s brothers, who died in World War I.

She was joined by Queen Camilla, 79, as their husbands, Prince William and King Charles III, took part in the ceremony.

William, also 44, and Charles, 77, laid wreaths during the service.

Prince Harry — who returned to live in the UK with his wife, Meghan Markle, in late August — did not attend the ceremony with his estranged family.

Instead, Diana’s youngest son, who sported his medals and a poppy pin, kept a low profile while standing on a side street with locals in Brackley, Northamptonshire.

The Duke of Sussex, 42, was not joined by Markle, 45, or their two children: Prince Archie, 7, and Princess Lilibet, 5.

Middleton, meanwhile, annually steps out to the memorial event and often makes sure to wear Diana’s beloved earrings.

Last year, she styled the pearls with a black-and-white polka-dot dress and a black headpiece while at Westminster Abbey.

The mom of three also wore the earrings with a black coat dress to the 2024 service at the Royal Albert Hall.

Diana died at the age of 36 in 1997 after her vehicle crashed inside Paris’ Pont de l’Alma tunnel while being chased by paparazzi.

The former Princess of Wales was in the car with her boyfriend, Dodi Fayed, and driver Henri Paul, who also died.

She was previously wed to Charles, whom she had divorced the year prior.
