Sienna Miller Is Now A Mum Of Three

For the offspring of famous parents, the public appearances often start while they’re still in utero, what with the A-list tradition of red-carpet bump reveals. Think of Beyoncé, then expecting Blue Ivy, at the 2011 MTV Video Music Awards; or Rihanna revealing her first pregnancy in a bright pink Karl Lagerfeld puffer in 2022 (only to outdo herself soon after at her Super Bowl performance, her second pregnancy visible beneath her custom Loewe jumpsuit), or Sienna Miller, confirming she was expecting her third child in a sheer Givenchy dress at last year’s Fashion Awards. Miller has now given birth, she confirmed to E! on Monday.

After keeping a relatively low profile last year, the actor delivered her surprise bump reveal in characteristic boho style (albeit a more elevated take than the early Noughties Glastonbury regalia and beaten-up cowboy boots that defined that decade). Fans will also remember another maternity style moment at Vogue World: London in 2023, where a pregnant Miller walked the red carpet in a Schiaparelli puffball skirt and ruched cropped shirt that quickly went viral.
