Irish actor and four-time Oscar nominee Saoirse Ronan may be engaged to be married, or she just has really stunning taste in jewelry. Actually, great taste whether it’s an engagement ring or not. 

Ronan has been spotted wearing a ring with a large stone on her left-hand ring finger, sparking rumors she might be headed toward marriage. Earlier in October, she sported it while leaving a fashion show, and she was seen wearing it while walking a dog with partner Jack Lowden, a fellow actor, on Sunday. The dog’s name is Fran. The ring’s significance remains unconfirmed.

Ronan and Lowden acted opposite one another in 2018’s Mary Queen of Scots, in which Ronan’s marry reluctantly agrees to marry Lord Darnley (played by Lowden). They cause a constitutional crisis with their marriage, and then Darnley is discovered in bed with Mary’s private secretary, David Rizzio. Oops.

Ronan and Lowden also co-founded a production company, Arcade Pictures, together.

In February, Lowden told Esquire UK that producing with Ronan was “a great adventure.”

“Saoirse is, first and foremost, one of the best actors in the world, so to work with her in that way and help in any way I could was great,” he said. “It’s hopefully the first of many—it was wonderful.”

Ronan, too, speaks highly of Lowden, telling Harper’s Bazaar, “When a person you respect as much as I do him says that, it means more than anyone else’s opinion.”

When asked if that praise was as good as an Oscar, she responded, “Well, I mean, an Oscar would also help.”

Representatives for Ronan and Lowden did not immediately return requests for comment.
