Sienna Miller, 44, addresses the ongoing fetishization of older women dating younger men amid her relationship with 29-year-old Oli Green. The couple, who share a 15-year age gap, welcomed a daughter in 2023 and now expects their second child together, marking Sienna’s third pregnancy overall.
Views on Age-Gap Dynamics
Sienna reflects on her early acting days, recalling an audition at age 21 to play the love interest opposite a 45-year-old actor. “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,” she states.
The pair began dating in 2021. Oli Green, also an actor, appeared in A Good Person alongside Florence Pugh and Morgan Freeman in 2023, and featured in an episode of The Crown with Imelda Staunton and Dominic West that same year.
Pregnancy Updates and Cravings
Sienna debuted her baby bump at The Fashion Awards in December 2025. She shares current cravings for vinegary foods and peanut butter with jam on toast. She also anticipates postpartum hair loss again, noting, “It’s these bits—they’re just starting to grow back properly and now it’s all going to go again,” while twirling strands around her fingers.
The actress looks forward to taking time off this year to bond with her children, including 13-year-old daughter Marlowe from her previous relationship with ex-partner Tom Sturridge.
Praise for Partner and Generational Shifts
Sienna describes falling unexpectedly in love with Oli. “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,'” she recounts.
She highlights differences in how younger men respect women: “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.”
Family and Career Resurgence
Sienna and Tom Sturridge, 40, dated for four years before splitting in 2015. They remain close, with Sienna calling him her “best friend” as they co-parent Marlowe.
Her breakthrough roles in Layer Cake and Alfie arrived 20 years ago. After a quieter period, 2024 brought a career revival. Just five months postpartum, she shone at the Cannes Film Festival promoting Kevin Costner’s western epic Horizon: An American Saga. Critics praised her portrayal of Frances Kittredge, highlighting her impeccable American accent. Time magazine deemed her “far and away the best thing” in the film despite mixed reviews.
