Why the Sienna Miller pregnancy reveal stood out

Miller walked into the Royal Albert Hall in a sheer white gown worn over small shorts, while Green stayed by her side in a dark suit with thin pinstripes. Miller's dress was light and easy, nothing loud, but the bump showed at once. Photos spread online within minutes and people picked up on the moment quickly.

Miller already has a daughter with Green, born in 2023, and a 13-year-old daughter, Marlowe, from her earlier relationship with Tom Sturridge. This third pregnancy marks another steady chapter for the pair.

How Sienna Miller has spoken about motherhood before

Miller has been open in interviews about the pressure she felt around fertility when she turned 40. In a 2022 conversation with Elle UK, she said the noise around “should I have more?” became overwhelming. She also confirmed at the time that she had frozen her eggs, simply to feel more in control of her options.

She has said she hoped to reach a point where she would not have to joke about being an older mother, a point that many fans noted. Looking back at her remarks now, the new pregnancy explains the quiet periods and the lack of public events over the past few months.
