Sienna Miller: ‘Layer Cake’ actress reveals pregnancy

Sienna Miller is expecting her third child, revealing her bump at the 2025 Fashion Awards in London.

The actress, 43, appeared on the red carpet at the Royal Albert Hall wearing a sheer white dress over mini shorts, styling her hair in loose waves with statement earrings.

This will be Miller’s second baby with actor Oli Green, with whom she welcomed a daughter in late 2023. She is also mum to Marlowe, 13, whom she shares with ex-partner Tom Sturridge.

Miller and Green have been together since 2022. She has previously spoken about the pressure she felt to grow her family after turning 40, telling Elle UK that she froze eggs to ease the anxiety around fertility. In a later interview with Vogue, she reflected on the insecurities that can accompany becoming a mother later in life and said she hoped to reach a point where she no longer felt the need to joke about her age.

Earlier this year, Miller made a rare public appearance with Marlowe at her sister Savannah Miller’s Bridal Ballerina Breakfast in London. Another photo from the event showed Miller, Green and Marlowe together.
