The Anatomy of a Scandal star shared the news while sitting for an interview with E! News.
“It’s happened,” she said. “I have a tiny baby next door.”
Sienna didn’t share the name or gender of her baby.
“It feels like stringing sentences together is a bit challenging,” she joked. “I’m on very little sleep, but I’m madly in love with my baby.”
Sienna Miller is a mother of three. She shares a daughter, Marlowe, 12, with her ex, Tom Sturridge. She also welcomed a daughter in 2023 with her current boyfriend, and father of her newborn, Oli Green, 29.
Sienna Miller is Loving Pregnancy and Babies in Her 40s
The starlet broke an 8-year social media hiatus on March 20th to announce the pregnancy. In a post with no caption, she simply shared a photo of her baby bump. But she technically first shared the news when she showed up to the 2025 Fashion Awards in London to walk the red carpet on in December 2025. At the time, she was visibly pregnant.
Sienna Miller is enjoying a second round of motherhood. As she told Glamour in March, being pregnant in her 40s is much more enjoyable than 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 admitted. “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.'”
