Saoirse Ronan Marries Jack Lowden in Secret Ceremony in Scotland

Saoirse Ronan and Jack Lowden have tied the knot!

Per online Scottish civil marriage registry records viewed by PEOPLE, the couple — listed on the documents as Saoirse Una Ronan and Jack Andrew Lowden — said their "I dos" in Edinburgh.

According to the Irish Independent, the ceremony — which reportedly took place last weekend — was "low-key" and "only a handful of the couple’s closest friends were present." 

The publication also stated that "all the guests were sworn to secrecy." during the ceremony, which occurred at Edinburgh Central Registrar’s Office, located at the City Chambers, per the outlet.

Reps for Ronan, 30, and Lowden, 34, didn't immediately respond when contacted by PEOPLE for comment.

The news comes after the Little Women actress first sparked engagement rumors in October when she stepped out with a diamond ring on her left hand at the Louis Vuitton Womenswear Spring-Summer 2024 show in Paris.

The couple tends to keep their private lives on the down low, and have been quietly dating for a few years.

Last month, Lowden shared a rare personal photo on Instagram showing the pair cuddling up while attending Glastonbury Festival in Somerset, England.

The couple previously co-founded the production company Arcade Pictures together. However, Variety reported in February that they were stepping down after releasing the company's debut feature, The Outrun, which had its world premiere at the Sundance Film Festival earlier this year.

Lowden founded Arcade Pictures in 2019 with producer Dominic Norris, with Ronan later joining as a company director in 2021. Despite the changes, Norris will remain in his current role at Arcade Pictures, the outlet reported at the time.

Back in 2018, Lowden spoke highly about working with Ronan for the filming of Mary Queen of Scots. The pair are thought to have fallen in love while shooting the movie, which saw Ronan take on the role of Mary Stuart. Meanwhile, Lowden played her second husband, Henry Darnley.

While previously speaking during a panel with AOL, Lowden said, "It was remarkable working with Saoirse."

"The woman is a force of nature on and off screen, and utterly fearless and a brilliant leader as well. For being 24 years old, it's just constantly amazing to me, not just her work but how she is on a set is amazing," he added at the time.

Ronan told PEOPLE in 2022 that she and Lowden "have very similar tastes."

"So I completely trust his eye," she added at the time. "And I know when he says something's working, it really is, because he doesn't ever sugarcoat anything. So I think that really helps, having someone that you really trust. And he's a sort of typical Scot, where if there's a problem, he's the first one to try and solve it."
