A Surprise Reveal

The news comes after Miller famously debuted her baby bump on the blue carpet at the Fashion Awards in December. This wasn't the first time the actress used a high-profile fashion event for a personal announcement; she previously revealed her second pregnancy at the 2023 Vogue World Show.

The new arrival joins Miller’s other children: a two-year-old with Green and her 12-year-old daughter, Marlowe, whom she shares with ex-fiancé Tom Sturridge.

Breaking Stereotypes with Oli Green

Sienna and Oli, 29, have been dating since 2021. The actress has been vocal about their 15-year age gap, often challenging the "fetishized" view society has of older women dating younger men.

Miller praised Green’s generation for having a "level playing field" when it comes to respecting women. She noted that his maturity and wisdom made it easy for her to fall in love, despite her initial hesitation about his age. Green is also a rising star in his own right, known for his roles in A Good Person and The Crown.

The Postpartum Reality

Even for a seasoned star, the challenges of motherhood remain the same. Miller joked about her current cravings, which included plenty of vinegar and peanut butter on toast, and lamented the return of "postpartum hair loss."

"It's just starting to grow back properly, and now it's all going to go again," she shared with a laugh. Despite the physical toll, Miller seems to be enjoying this quiet chapter of her life away from the Hollywood spotlight.
