Sienna Miller Confirms Pregnancy With Baby Number Three at London Fashion Awards

Sienna Miller has confirmed she is expecting her third child after debuting her baby bump on the red carpet at the 2025 Fashion Awards in London on December 1. The actress, 43, appeared glowing as she arrived at the Royal Albert Hall wearing a sheer white gown that proudly showcased her pregnancy.

This will be Miller’s second child with boyfriend Oli Green, 28. The couple welcomed their first daughter together in late 2023. Miller is also mother to 13 year old daughter Marlowe, whom she shares with former partner Tom Sturridge.

Miller and Green have been together since 2022 and have largely kept their relationship private. Over the years, the actress has spoken candidly about the pressures women face when it comes to motherhood later in life and previously revealed she had frozen her eggs to preserve future options.

In earlier interviews, Miller said that while biological expectations can weigh heavily on women over 40, she ultimately learned to let go of anxiety and allow life to unfold naturally. Friends close to the actress say she is embracing this pregnancy with confidence and joy.

The actress recently made rare public appearances with her daughters and continues to balance motherhood with her career. Industry insiders say Miller remains selective about her projects while prioritizing family life.

No further details about the pregnancy timeline have been publicly disclosed.
