Saoirse Ronan's husband Jack Lowden keeps disappointing her by refusing to perform a "cheesy karaoke duet" of her choice

Appearing on 'The Tonight Show Starring Jimmy Fallon' on Thursday (07.11.24), Saoirse said: "I've been desperate for myself and my husband Jack to do a cheesy karaoke duet.

"It's 'Shallow' from 'A Star is Born'. I want him to be my Bradley, and I'll be his Gaga.

"And he won't do it. He hasn't committed.

"And I'm sort of like, well, what's marriage for? You know what I mean? What are we doing here?"

Saoirse, 30, and Jack, 34, started dating in 2018 and got married in 2024 in a wedding ceremony in Edinburgh, Scotland.

Jack worked as a producer on 'The Outrun' and was instrumental in convincing her to take on the role of Rona, a young woman recently out of rehab for alcoholism who returns home to the Orkney Islands in Scotland to see her father.

Saoirse says Jack - who co-starred with her in 2018 historical drama 'Mary Queen of Scots' - is coming round to the idea of collaborating with his wife more on screen and stage.

She told USA Today: "Jack didn't want to for a long time, but I've now convinced him that's a great idea.

"I'd really like to do something together on stage.

"Jack is a lot calmer than I am. He's my voice of reason.

"But as a duo, we've both been on film sets our whole lives, so we have an appreciation of what we're asking actors to do. We always want them to feel safe."

'Fighting with My Family' star Jack admits working with his wife ends the problem of them being separated for long periods due to their acting commitments.

He told The Times newspaper: "Making work together solves that problem, so that's another reason why we want to do more together.

"'The Outrun' gave us such a taste for it. And it can be a lonely thing, this profession."
