Sienna Miller Is Now A Mom Of Three

Few celebrities have turned the maternity style moment into an art form quite like Sienna Miller. According to Vogue, she confirmed her third pregnancy at last year's Fashion Awards in a sheer Givenchy dress — and before that, she stopped the internet cold at Vogue World: London 2023 in a Schiaparelli puffball skirt and ruched cropped shirt. Even before the birth announcement, she was already making the bump a full editorial statement.

The Lineage

She's not alone in the tradition, of course. Beyoncé unveiled Blue Ivy at the 2011 MTV VMAs; Rihanna dropped her first pregnancy in a Karl Lagerfeld puffer, then escalated to a custom Loewe jumpsuit at the Super Bowl for the second. But where their reveals leaned into spectacle, Miller's have always felt more like — well, her. Effortless, tactile, a little undone in the best possible way.

On Monday, Miller confirmed to E! that she has given birth, welcoming her second child with boyfriend Oli Green. The couple already share a daughter born in December 2023, and Miller's eldest, 13-year-old Marlowe, is from her relationship with actor Tom Sturridge. Three kids. Still the most stylish woman in any room.

What comes next, fashion-wise, is the real conversation. Miller built the blueprint for bohemian dressing before TikTok had the audacity to rebrand it as a trend — the braided headbands, the billowy blouses, the battered suede. She was doing "coastal grandmother" and "indie sleaze" before either phrase existed. Postpartum, expect the same: floaty silhouettes, something '70s-adjacent, an outfit that looks thrown together and costs more than your rent.

The rest of celebrity maternity style may be about the reveal, but Sienna Miller's is about the entire run — a reminder that personal style doesn't pause for pregnancy, and it certainly doesn't pause for a newborn.
