In a stunning appearance at London’s 2025 Fashion Awards, acclaimed actress Sienna Miller proudly showcased her pregnancy, marking her third journey into motherhood. The 43-year-old Factory Girl star captivated attendees in an elegant sheer white Givenchy gown that beautifully accentuated her growing baby bump, radiating maternal joy throughout the prestigious event.
Miller’s expanding family includes 13-year-old daughter Marlowe from her previous relationship with actor Tom Sturridge, and a 23-month-old daughter with current partner Oli Green. The actress previously acknowledged the initial adjustment period for Marlowe in embracing her role as an older sibling, noting that her teenager has now fully embraced the experience with enthusiasm.
The family dynamics appear particularly heartwarming, with Miller observing that her youngest daughter already demonstrates clear admiration for her big sister, creating a mutually affectionate bond between the siblings. This pregnancy realization follows Miller’s candid discussions about the biological challenges women face when conceiving after 40, leading her to pursue egg freezing as a proactive measure for family planning.
Despite the pressures surrounding age-related fertility concerns, Miller has adopted a more relaxed perspective toward expanding her family, finding peace in knowing she has taken appropriate medical precautions. The announcement comes as Miller continues to successfully balance her thriving acting career with her growing family responsibilities, celebrating both personal and professional milestones with equal grace.
