Princess Diana’s former bodyguard Ken Wharfe spoke out about Kristen Stewart’s portrayal of the late royal and praised her performance in Pablo Larraín’s 2021 drama “Spencer.”

Wharfe served as the Princess of Wales’ personal protection officer from 1989 to 1993, which means he was her bodyguard at the time when the movie takes place: in 1991, during a three-day period over Christmastime in Sandringham with the rest of the royal family.

“Out of all the people who have played Diana over the past 10 years, she’s the closest to her,” he told People about the “Twilight Saga” star. “She managed to perfect her mannerisms.”

The film depicted some of the struggles Diana encountered amid her rocky marriage to Prince Charles as well as being a mother to her sons William and Harry.

“It was purgatory for her,” Wharfe continued, adding that Diana often “confined herself to spending time in the kitchen with the chef or with people like me, in the hope that time would while away, and she could get back to London.”

Stewart, 31, also recently discussed what it was like to put on Diana’s iconic wedding dress — well, a replica that is.

“Putting that on was a spooky day,” she told Entertainment Tonight on the red carpet at the “Spencer” premiere late last month. The wedding dress scene is just one of many included in a montage of several moments that flash before her eyes during the course of the movie.

“Even though I play her as a speculatively 29, 30-year-old person, we still wanted to give a taste of the scope of her life,” Stewart shared. “Kind of touch on every part.”

Diana was further immortalized this year when a Broadway show entitled “Diana: The Musical” hit the stage. Her life and legacy will be examined further in Season 5 of Netflix’s “The Crown,” out next year.
