Sienna Miller made a rare red carpet appearance with partner Oli Green on Friday, May 15, 2026, as the couple enjoyed a glamorous evening out in New York City following the arrival of their second child together. The actress, 44, attended the world premiere of Amazon MGM's Tom Clancy's Jack Ryan: Ghost War at Regal Times Square, where she posed alongside Oli and fellow stars including John Krasinski, Michael Kelly and producer Julie Rappaport.
Miller confirmed the news of her new addition in an interview published on 11 May, gushing that she is 'madly in love' with the newest addition to her growing family. 'It's happened. I have a tiny baby next door,' she told E! News. 'It feels like stringing sentences together is a bit challenging. I'm on very little sleep but I'm madly in love with my baby.'
For the occasion, Miller embraced understated elegance in a flowing strapless grey gown featuring a softly structured silhouette and oversized draped design. The chic minimalist dress fell effortlessly to the floor and was paired with white pointed heels, statement silver earrings and sleek pulled-back hair that highlighted her glowing makeup. Oli, 29, complemented her sophisticated look in a tailored light grey suit teamed with a striped shirt and matching tie.
The outing marks one of the pair's most high-profile appearances since welcoming their daughter in 2024. Miller is also mother to daughter Marlowe, whom she shares with ex-partner Tom Sturridge. Miller and Oli have been together since 2021 and have gradually become one of the fashion world's most quietly admired couples thanks to their coordinated style and low-key approach to fame.
