Actress Sienna Miller, expecting her second child with partner Oli Green, and her third overall, announced her pregnancy at the 2025 Fashion Awards in London.
The 43-year-old star, famed for her role in Factory Girl, showcased her blossoming baby bump in a sheer white Givenchy gown, exuding maternal happiness on the red carpet, as reported by E! News.
She is also the mother of a 13-year-old daughter, Marlowe, with ex Tom Sturridge, and a 23-month-old daughter with Oli.
As Marlowe gets ready to become a big sister again, Miller previously mentioned that adjusting to Marlowe’s role as an older sibling took some time. “Initially, it was overwhelming for her,” she shared with E! News in June 2024, “but now she’s thrilled.”
The bond between the sisters seems mutual, with Miller noting that her toddler “already idolizes” Marlowe and “lights up every time she sees her.” She added, “Now that the baby can respond, [she] is clearly in love with her big sister.”
Miller has always expressed her wish to expand her family, even acknowledging the difficulties women face conceiving after 40. “The pressure… about having kids, whether I should have more, and why I haven’t, which can be overwhelming,” she told Elle UK in April 2022. “Biology is incredibly harsh on women in that era, that’s the headline, or at least it was for me,” according to the outlet.
To plan ahead, Miller froze her eggs to ease the process of growing her family. “Having been focused on the need for another child, I’m now at peace with the idea that if it happens, it happens,” she explained. “That existential pressure has lifted,” as reported by E! News.
Miller’s pregnancy news arrives as she continues to embrace motherhood, balancing her acting career and public engagements, celebrating both personal and professional milestones.
