Sienna Miller Welcomes Second Child with Oli Green
Sienna Miller, the 44-year-old actress, has welcomed her second child with her partner, model Oli Green. The couple already shares a daughter, who is two years old, and this new addition brings more joy to their family. In an interview with E! News, Sienna shared her excitement about the new arrival, saying, “It’s happened. I have a tiny baby next door. 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 is currently promoting her latest film, Jack Ryan: Ghost War, and used the opportunity to share the news of her pregnancy during the promotional interview. This comes after she previously revealed her third pregnancy at the Fashion Awards in December, where she made her announcement with a statement look on the blue carpet outside the Royal Albert Hall in London.
A History of Red Carpet Announcements
This isn’t the first time that Sienna has used a red carpet event to announce her pregnancy. In September 2023, she revealed she was pregnant with her second child at the star-studded Vogue World Show. She walked the red carpet at London’s Theatre Royal Drury Lane in a Schiaparelli puffball skirt and a cropped shirt that showcased her baby bump.
Sienna has spoken openly about her relationship with Oli, describing how it began. In an interview with Harper’s Bazaar, she said, “I didn’t expect to take it seriously and then quite quickly, I fell in love. I wasn’t like, ‘I’m gonna get a younger boyfriend.’ It was more, ‘F***! Why are you young? That’s so annoying.’ There is a difference in the way that generation of men respect women. 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.”
Addressing Age Dynamics in Relationships
Sienna has also spoken about the challenges faced by older women in relationships with younger men. In an interview with Grazia, she reflected on the early days of her acting career, when she once auditioned to play the love interest of a 45-year-old actor when she was 21. She said, “Things have moved on since then, but the idea of an older woman with a younger man, for example, is still fetishised rather than normalised – there’s a disparity there that I would love to see disappear.”

Life with Oli Green
Sienna and Oli first began dating in 2021. Oli is also an actor and has appeared alongside Florence Pugh and Morgan Freeman in the 2023 film A Good Person. He also starred in an episode of The Crown in the same year with Imelda Staunton and Dominic West.
During her recent interview, Sienna also spoke about her cravings during pregnancy. She mentioned being hooked on vinegary things and enjoying a lot of peanut butter and jam on toast. However, she also expressed some frustration about postpartum hair loss. “It’s these bits,” she said, twirling a few hairs around her fingers. “They’re just starting to grow back properly and now it’s all going to go again.”



A Family Life in Focus
Sienna is also a mother to Marlowe, who is 13 years old. She shares the child with her ex-fiancé, Tom Sturridge, whom she dated for four years before splitting in 2015. Despite the separation, the pair remains on good terms, with Sienna calling Tom her “best friend” while they co-parent their daughter.
As she continues to balance her career and family life, Sienna remains a prominent figure in the entertainment industry, known for her talent, charm, and candid approach to discussing personal and societal issues.
