They said, “I do.”

Kim Cattrall married her longtime partner, Russell Thomas, in an intimate wedding ceremony in London on Thursday.

The pair were joined by 12 of their closest friends and family members as they tied the knot at Chelsea Old Town Hall, per People.

For her big day, Cattrall, 69, reportedly wore a refined Dior suit that was styled by her longtime collaborator, Patricia Field. She was said to have paired her wedding outfit with Cornelia James gloves and a hat designed by Philip Treacy.

Thomas, meanwhile, reportedly sported a custom suit by Richard James.

The Post has reached out to Cattrall’s reps for comment.

Cattrall met her new hubby in 2016 when he was working as a sound engineer at the BBC.

“He was an actor originally,” the “Sex and the City” alum shared during an interview with the Times of London earlier this year. “He’s had an incredibly interesting life and really done it on his terms.

“He’s a bit of a rebel, which I love,” she added.

Cattrall said that almost a decade later, they were still head over heels for each other.

“We’ve been together almost 10 years now,” she said. “And we’ve had a blast. We’ve just had so much fun.”

Cattrall also called Thomas, 55, a “firecracker” during an interview with People in 2020.

“I’m very comfortable around him,” she told the outlet at the time. “He’s a firecracker, and he’s got a wicked sense of humor. And he’s easy on the eyes!

“I love him,” she added. “And he was worth waiting for.”

Cattrall, who played the iconic Samantha Jones in “Sex and the City,” opened up about her and her partner’s life together most recently in October.

She gushed over the couple’s home on Vancouver Island, which she called their “hideaway” and “paradise.”

“It’s long walks. It’s reading books I’ve never had the time to read — or reread. I love women’s fiction. It’s more solitary, just me and my partner,” she told People less than two months before her and Thomas’ wedding.

But Vancouver Island isn’t the only place the “Police Academy” alum and her longtime love spend their time, because they regularly visit England and the Big Apple as well.

“I also spend time in London, which is a great deal of where I’ve been the last 15, 20 years,” she shared. “And then there’s New York City, which will always be in my heart.”

This will mark Cattrall’s fourth marriage in almost 50 years.

She and her first husband, Larry Davis, were married from 1977 to 1979. Cattrall went on to marry Andre J. Lyon in 1982 before divorcing in 1989. She and her third husband, Mark Levinson, were married from 1998 to 2004.
