The actress is currently working on a film adaptation of the John le Carré book The Night Manager.

She and husband Ed, who live with their two children in Peckham, South London, are also expecting their third child this August.

Olivia says that when she found out she was pregnant, she asked producers of The Night Manager if they could make her intelligence officer character pregnant as well. They agreed.

The actress has had all her children in August - prompting her to joke that Ed finds her very attractive in November.

"It was love at first sight with Ed," she recalls, in a previous interview with the Mail in 2013. "He was studying law at Cambridge and I was at the teacher training college. We met doing drama at the Footlights [the university dramatic club]. He walked in and it was like a thunderbolt. I thought, ‘There’s the bloke I’m going to marry.’

"He's totally supportive," she adds. "He started out acting but the work just dried up. And, actually, for him I think it was a bit of a relief because he’d always wanted to write and he’s brilliant at it. He is working on a novel now and he’s quite secretive about the process. Ed being at home also means that he can look after the children if I’m away, and he’s a far better parent than me. So, although I miss the kids terribly if I’m away working, I know our little boys are in the best possible hands. When I get back they go, 'Oh no, she’s not going to cook is she? She’s bound to burn something!'"
