Actress Sienna Miller has welcomed her second child with her model partner Oli Green. The 44-year-old star, who already shares a two-year-old daughter with the 29-year-old model, and has 13-year-old Marlowe from her previous relationship with Tom Sturridge, shared the news with E! News: '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.'
Sienna announced her third pregnancy by revealing her blossoming bump at the star-studded Fashion Awards in December. She made the revelation with a statement look on the blue carpet outside the Royal Albert Hall in London. This is not the first time Sienna has used a red carpet at a fashion event to announce she is expecting. In September 2023, she revealed she was pregnant with her second child at the Vogue World Show, walking the red carpet at London's Theatre Royal Drury Lane in a Schiaparelli puffball skirt and a cropped shirt that showcased her baby bump.
Speaking previously about Oli, Sienna told Harper's Bazaar: '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. I see it in his female friends as well as in the men.'
Sienna has also spoken about the fetishisation of older women with younger men. In an interview with Grazia, she recalled early in her acting career auditioning 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.'
Sienna and Oli first began dating in 2021. Oli is also an actor and has starred alongside Florence Pugh and Morgan Freeman in 2023's A Good Person, and Imelda Staunton and Dominic West in an episode of The Crown the same year. The actress, who announced her current pregnancy at The Fashion Awards in December, also discussed her cravings. 'I'm hooked on vinegary things at the moment,' she said, adding that she has also been indulging in a lot of peanut butter and jam on toast. Sienna lamented having to go through another round of 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.'
Sienna dated Tom Sturridge, 40, for four years and they split in 2015. They are still on good terms, with Sienna calling Tom her 'best friend' whilst they co-parent Marlowe.
