“Curb Your Enthusiasm” actress Sienna Miller just revealed she’s pregnant, and showed off her adorable bump in a flowing white gown. Miller, who is remembered for her unforgettable cover on the September 2007 issue of Vogue which inspired the 2009 documentary “The September Issue,” embodied goddess vibes as she posed on December 1 as she posed at The Fashion Awards 2025 in London.

Pregnant Sienna Miller Glows at the Fashion Awards 2025
Miller posed on the red carpet and worked the cameras with ease at the London appearance. Her flowing blonde locks were wavy and free, and she accessorized her airy white pleated gown with dangly earrings.
Vogue called the reveal “a fab personal PR move” in a report published the same day, and reminded fans this is not Miller’s first red carpet walk with a baby on board. She was pregnant with her second child, a daughter with actor and model Oli Green, when she walked the carpet at Vogue World: 2023 in Schiaparelli.
GettyWho Is Sienna Miller Dating?
Sienna Miller’s current partner is Oli Green. The 28-year-old British model and actor is known for his 2025 role in “Bridget Jones: Mad About the Boy,” among others. US Weekly’s relationship timeline for Miller and Green says they first met a mutual friend’s Halloween party.
The outlet says Miller told British Vogue in 2023 that her first thoughts on the dashing younger man were, “This is not going to go anywhere,” and “This is absurd.”
However, Miller says Green “worked hard” to convince her to go on a date.
Green was at Miller’s side for her pregnancy reveal on December 1, 2025. They share one other child, who was born in 2023. Miller welcomed her oldest child, a daughter named Marlowe, in 2025 with her ex, Tom Sturridge. Prior to dating Sturridge, the report says she dated Jude Law, who made headlines for taking a spill at the 2025 Venice Film Festival, from 2004 to 2011.
In early 2022, the outlet says she was seen spending time with Green in NYC alongside “Jungle Cruise” actress Emily Blunt.
In March of 2022, the pair made their red carpet debut together before welcoming their first child the following year.
Why’d she wear her nightie. Do people have no class any more
I thought the same thing. Whatever happened to being classy?
I see London, I see France, I see Sienna’s underpants. Class has nothing to do with money.
