Sienna Miller and her partner Oli Green left the Curzon Mayfair in London together after attending the European premiere of the film Swiped on Thursday evening, the couple appearing relaxed as they made their way to their car.
Miller, 43, wore a baby-blue button-up shirt layered under a dark brown bomber jacket, black high-waisted flared jeans and black leather boots. Green, 28, wore a blue denim shirt over a white T-shirt with light-wash denim jeans and brown suede shoes. The pair walked side by side, with Miller carrying an oversized black textured shoulder bag and wearing a cluster of delicate earrings.
Earlier on the red carpet, Miller posed for photographs ahead of the screening. Swiped, a forthcoming drama starring Lily James as Whitney Wolfe Herd, portrays a tech entrepreneur breaking into a male-dominated industry by launching two dating apps and becoming a young self-made billionaire. The premiere drew a number of industry figures to the Mayfair cinema for the European showcase.
Miller and Green began dating in 2022 and welcomed their first child together last year. Their age difference — Green is 15 years younger than Miller — has been the subject of attention in previous interviews. Speaking to Harper's Bazaar, Miller said she had not expected to take the relationship seriously but that she "quite quickly... fell in love," adding, "I wasn't like, 'I'm gonna get a younger boyfriend.' It was more, 'F*ck! Why are you young? That's so annoying.'"
She has also discussed generational differences in attitudes toward women, saying in that interview that Green and his friends show a ‘‘slightly more level playing field’’ and describing him as "very wise and well-adjusted."
Miller continues to co-parent her daughter Marlowe, 12, with actor Tom Sturridge, her partner from 2011 to 2015. In a separate interview with Vogue UK, Miller said she was "really happy" for Sturridge following his engagement to Alexa Chung and described their ongoing relationship as amicable, referring to Sturridge as her "best friend." Miller has recounted the practicalities of their co-parenting arrangement, including lighthearted anecdotes about shared clothing between families.
The screening at Curzon Mayfair served as a high-profile stop on Swiped's rollout and offered one of the first public opportunities to see Miller and Green together at a film industry event since the birth of their child. The film's wider release and additional promotional appearances are expected in coming months.
