Sienna Miller is currently expecting her third baby — and she says being pregnant in her 40s “is the best.”
Miller, 44, opened up about her pregnancy in an interview with Glamour published on Monday, March 23, noting that it’s been “easier” to be pregnant in her 40s than it was in her 20s.
“Having had a baby at 29, and then having a baby at 42, and now 44, it’s so much easier when you don’t have the conflict of feeling scattered and like you want to be doing X, Y, Z,” she explained. “If I’m in bed at 9 p.m. with a book, I’m so happy now. And now I’ve got the excuse to do it. Life is in a more grounded space. I think the 30s are chaos. You’re like, ‘I want to settle down. I want kids.’”
Miller is currently expecting her third baby, her second with boyfriend Oli Green. Their first child, a girl, arrived in December 2023. The actress also shares daughter Marlowe, 13, with ex Tom Sturridge.

The Anatomy of a Scandal alum went on to push back against the idea that she’s too “old” to be having a baby.
“By the time you hit 40, you’re like, ‘I kind of know who I am. I don’t really give a s*** about what anyone else thinks.’ I’m a much more grounded human,” she said. “We don’t judge men who are having kids in their 80s. Why on earth is there any sort of narrative?”
Miller noted that she did freeze her eggs — which she called a “really revealing” process — but didn’t use them.
“I was really fortunately able just to get pregnant, but it was an existential relief having done that in my late 30s,” she noted before reminding fans not to fret over how “old” they are. “When we’re 60, we’ll be like, ‘God, at 40 and when I was old.’ It’s such a narrative that’s so subscribed, and it’s a way of monetizing our insecurity, and we have to stop it.”

She added, “It’s also good luck. You’re lucky if you get to get older. And getting pregnant and being older, I think is a biohack. You get all those hormones, you get all that blood. It’s great. I’m here for it.”
Miller and Green, 29, started dating in 2021. She previously defended their 15-year age gap, joking that she initially found his age “annoying” but soon “fell in love.”
“There is a difference in the way that generation of men respect women,” she told Harper’s Bazaar UK in June 2024. “It’s specific to him, he is very wise and well-adjusted, but I do believe it’s also that generation. They have grown up with a slightly more level playing field. I see it in his female friends as well as in the men.”
