Sienna Miller Embraces Motherhood for Third Time at 44
While she has not yet publicly shared the baby's name or sex, Miller expressed her joy following the delivery. "It's happened," Miller told E! News. "I have a tiny baby next door." The birth marks a significant milestone for Miller, who has been vocal about the different perspective she holds as a mother in her 40s.
She is already a parent to her 13-year-old daughter, Marlowe, whom she shares with ex-partner Tom Sturridge, and a two-year-old daughter with Green. In her conversation with E! News, Miller admitted that the newborn phase brings its usual challenges, noting, "It feels like stringing sentences together is a bit challenging. I'm on very little sleep but I'm madly in love with my baby." The actress previously spoke about the "existential threat" of the biological clock during her 30s, explaining that she chose to freeze her eggs before conceiving naturally.
She has described the experience of being pregnant and parenting in her 40s as "the best," citing a more "grounded" sense of self compared to her earlier years.
A Growing Family with Oli Green
Miller and Oli Green, a 29-year-old actor and model, have been romantically linked since late 2021. The couple first went public at a 2022 BAFTA afterparty and have since shared several high-profile moments, including Miller debuting her most recent pregnancy on the red carpet at the 2025 Fashion Awards in London.
Reflecting on her life as a mother of three, Miller noted that her priorities have shifted toward a more relaxed lifestyle. "If I'm in bed at 9 p.m. with a book, I'm so happy now," she shared in earlier interviews regarding her pregnancy. "And now I've got the excuse to do it."
