Sianna Miller stepped onto the London red carpet for the premiere of the new series War, sharing the stage with veteran actor Dominic West. The 44‑year‑old appeared just four months after giving birth, drawing immediate praise from onlookers.

Daily Mail reporters noted that she looked flawless, with her glow and confident posture suggesting she had hardly missed a beat despite the recent delivery.

In a recent Vogue interview, the actress reflected on becoming a mother at 40, saying she felt wonderful during the postpartum period and never imagined she would conceive again at her age.

Her third child, born when she was 44, was also unexpected. The star described the surprise pregnancy as a happy twist in her life.

Miller is mother to three children: a daughter, Marlowe, from her previous relationship with actor Tom Sturridge, and two younger kids she shares with fiancé Oli Green.

The newest baby arrived in April, and the actress returned to the set of War just three weeks later, underscoring her dedication to both family and career.

She announced the pregnancy publicly at a high‑profile society event, turning heads with a stylish reveal that sparked conversation across entertainment circles.

Fans can now look forward to seeing her performance in the series, where she leads alongside West, as the show prepares for its upcoming broadcast.
