British actress and style icon Sienna Miller has confirmed she is expecting her third child, making the announcement in unmistakably glamorous fashion at the 2025 Fashion Awards in London. The 43-year-old appeared on the red carpet in a sheer, lingerie-inspired Givenchy gown that publicly showcased her baby bump, immediately becoming one of the most talked-about moments of the event.
Miller, who is expecting the child with her partner, actor Oli Green, was widely praised by fashion observers and fellow celebrities for blending personal news with a striking couture statement. This will be the couple’s second child together, adding to Miller’s growing family, which also includes her first daughter, Marlowe.
A Red-Carpet Reveal That Blended Style and Personal Milestone
Sienna Miller’s appearance at the 2025 Fashion Awards quickly became the night’s highlight. Arriving in a flowing white Givenchy gown, she opted for a look that was both delicate and bold. The sheer, lingerie-themed design, part of Sarah Burton’s Spring 2026 collection, offered an ethereal silhouette that allowed her baby bump to take center stage.
Fashion journalists from outlets including Vogue, InStyle, and People described the ensemble as a deliberate nod to early-2000s bohemian chic—a style Miller helped popularize. Many noted that the actress has a long history of turning maternity fashion into a form of expression, and this latest reveal further cements her reputation for redefining red-carpet expectations.
Public Reaction and Media Coverage
Media outlets across Europe and the United States quickly picked up the story, praising both the elegance of the reveal and the openness of the announcement. Vogue UK reported that Miller’s presence “captivated the carpet,” while InStyle highlighted her willingness to embrace a transparent, boundary-pushing wardrobe during pregnancy.
Despite the global attention, Miller has not issued a formal statement regarding her pregnancy. Her representatives have also remained silent, leaving the red-carpet moment as the sole public confirmation.
A Growing Family and Evolving Narrative
This marks Sienna Miller’s third child and her second with partner Oli Green, with whom she welcomed a daughter in early 2024. Her first daughter, Marlowe, was born in 2012 from her relationship with actor Tom Sturridge. Over the years, Sienna Miller has been open about the pressures women face when building families later in life, speaking candidly about topics such as fertility, egg-freezing, and societal expectations.
Her decision to reveal her pregnancy publicly through a fashion moment reflects a continued embrace of transparency and empowerment. Many commentators have framed the announcement as a statement on bodily autonomy and the evolving representation of motherhood in celebrity culture.
While no due date, medical details, or future plans have been disclosed, sources report that Sienna Miller appeared in high spirits throughout the event. Photographers captured her smiling and interacting warmly with guests, including designers and fellow actors. The simplicity of the reveal—delivered without a social-media campaign or official announcement—has fueled appreciation for its authenticity.
As the awards season continues, observers expect Sienna Miller’s maternity wardrobe to draw continued attention, potentially influencing upcoming fashion trends and setting the stage for more bold displays of pregnancy in the spotlight.
