Sienna Miller, 43, Surprises with Third Pregnancy Announcement... Shows Off Baby Bump in Sheer Look on the Red Carpet

Icon of 'Boho Chic', Sienna Miller (43) lit up the London night with her beautiful baby bump.

On December 2nd (local time), Sienna Miller appeared on the red carpet of 'The Fashion Awards 2025' at the Royal Albert Hall in London, officially announcing her third pregnancy by revealing her protruding belly. This is a joyous occasion about two years after giving birth to her second daughter with her 14-year-younger boyfriend, Oli Green (27), in January 2024.

Miller's choice that day was bold yet elegant. She wore an empire waist mesh dress from the 2026 Spring/Summer collection of Givenchy, led by designer Sarah Burton.

The sheer white dress revealed her beautiful baby bump without reservation, and she accentuated her look with pearl pendant earrings and pink fur sandals, showcasing her status as a 'fashion icon'. Initially standing alone on the red carpet, she later posed with her boyfriend Oli Green, displaying the happy smiles of expectant parents.

◆ A Blessing in Her 40s... "The Freedom Given by Egg Freezing"

This pregnancy holds even more special meaning for Miller. In a past interview with Elle UK, she expressed the pressure of pregnancy, stating, "Biology is very cruel to women in their 40s."

At that time, she confessed that she chose to freeze her eggs at 40 due to anxiety about whether she should have more children, and after much effort and waiting, she is now expecting a precious life in her mid-40s. She has two children, her first daughter Marlow (13) from her former fiancé Tom Sturridge and her first child with Oli Green.
