The British actress Sienna Miller left fans delighted after she unveiled her third pregnancy to the world while appearing at the British Fashion Awards on Monday.
Now the news is out, the Layer Cake star, 43, has no qualms about flaunting her blossoming baby bump as she did on Thursday evening in a rather striking dress!
Sienna's incredible reveal
The fun night out came just hours after Sienna made headlines, along with Ellie Goulding, for both revealing the joyful news they are expecting on the red carpet of the British Fashion Awards.
Sienna, who is expecting her second child with her boyfriend Oli Green, looked angelic, wearing a floor-length chiffon Chloe gown with a pair of white knickers and her baby bump fully on show. Completing her look were a pair of statement drop earrings.
This time, the Anatomy of a Scandal star chose mermaid-like waves as her go-to style for the evening.
HELLO!'s fashion and beauty news editor, Laura Sutcliffe, explains how Sienna is redefining fashion for women in their 40s. "As a fashion editor who has just turned 40, I was cheering Sienna on from the comfort of my living room on Monday night when I saw her at the Fashion Awards 2025, rocking a baby doll, see-through Givenchy dress. It's incredible to see a woman of that age wearing daring trends that people often associate with the Gen Z crowd.
"I thought she looked stunning! Sienna proves that age really is just a number - I genuinely cant think of anyone more stylish than her right now, no matter what age. Also, younger women use her as a blueprint - let's not forget she literally invented boho style, which is still hugely prolific today."
Meanwhile, British pop star Ellie, 38, who is already the mum to son, Arthur, whom she shares with her ex-husband Caspar Jopling, chose a tailored black capri pant, which she paired with a simple black crop top, allowing her beautiful bump to be shown.
Completing her look, she added a leather trench coat and pointed-toe pumps. This will be Ellie's first child with her boyfriend, Beau Minniear, 28.
