Actress Sienna Miller is sharing some wonderful news: she is expecting her third child.
The star, who is 43 years old, chose a major public event to make the announcement, arriving on the red carpet at the 2025 Fashion Awards in London on Monday night.
This new baby will be her second with her partner, actor Oli Green.
Sienna used the high-profile fashion event to debut her pregnancy in a truly memorable way. She walked the red carpet in a beautiful sheer white Givenchy gown.
The dress had a unique, lingerie-inspired design that perfectly highlighted her baby bump.
The American Sniper star looked joyful and radiant as she posed for cameras in the striking outfit.
Her public reveal maintains a tradition of using fashion moments to share big news, similar to how she previously showcased her pregnancy with her second child at another event.
This new arrival expands Miller’s family. She first became a mother in 2012, welcoming her daughter Marlowe with her ex-partner, Tom Sturridge.
She then had her second daughter, her first with Oli Green, in January 2024.
Sienna Miller has been very honest about the specific worries women face when they try to have children in their 40s.
She spoke in previous interviews about feeling a heavy pressure to grow her family as she approached age 40.
She made the choice to freeze her eggs at that time, explaining that she felt biology was unfair to women during that decade.
However, she noted that after taking that step, the major worry about having more children calmed down.
She now embraces a more relaxed perspective, feeling that if a pregnancy occurs, it occurs. This happy news finds the actress glowing and celebrating her expanding family.
