Sienna Miller Shakes NY in Feathered Mini‑Dress, Confirms Pregnancy

Sienna Miller turned heads on the red carpet of HBO’s *War* premiere in New York on Tuesday night, arriving in a striking feathered mini‑dress from designer Erdem. The 44‑year‑old showcased a black satin bodice that flowed into a skirt of huge white feathers, complemented by black heels and a loose up‑do.

Her blonde hair was styled in an effortless up‑do, and she finished the look with elaborate silver earrings.

Miller was flanked on the carpet by her co‑star Dominic West, who appeared sharp in a navy blue suit. West portrays Miller’s former partner, Morgan Henderson, in the legal drama that pits two elite London law firms against one another for victory.

The show follows their complex professional rivalry and personal history as Carla Duval and Morgan navigate high‑stakes courtroom battles.

The premiere arrives shortly after Miller revealed that she was pregnant during the entire filming of *War*. She was reportedly 35 weeks by the end of shooting and welcomed her third child in April, followed by a second baby with partner Oli Green in January 2024.

She also shares a 14‑year‑old daughter, Marlowe, with actor Tom Sturridge, whom she dated for four years until July 2015.

## Background & Context

*War* is a new drama that examines the cutthroat world of London’s high‑profile legal practice.

The narrative centers on two rival firms—Henderson & Partners and Duval & Co.—as they vie for dominance in the courtroom, while their leading attorneys, Carla Duval (Miller) and Morgan Henderson (West), confront a tangled web of past affection, professional ambition, and ethical dilemmas.

The series, written by a team that includes former legal counsel turned screenwriter, weaves courtroom strategy with personal intrigue to create a tense, character‑driven story.

Miller’s experience on set was described as physically demanding due to her pregnancy.

In a recent interview she said the filming schedule involved long days that left her “leaving and coming home in the dark.” She added that the work environment was intense yet supportive, noting that fellow pregnant co‑star Phoebe Fox “sat together, laughing over coffee between shots.” This camaraderie highlighted the inclusive atmosphere of the production, which accommodated both actresses’ needs through flexible scheduling and on‑set medical support.

Miller’s personal life has expanded rapidly in recent years. In April she gave birth to her third child, and in January 2024 welcomed another with Oli Green. Two months after the birth of their first child together, the couple announced their engagement.

Meanwhile, her daughter Marlowe, 14, is the product of a four‑year relationship with Sturridge that ended in 2015. These life events have added a new dimension to Miller’s public persona, drawing both admiration and curiosity from fans.
