Sienna Miller Is Pregnant With Baby No. 3, Her Second With Oli Green
Sienna Miller is bringing a maternal glow to the red carpet.
The Factory Girl actress is expecting her second baby with boyfriend Oli Green and third overall, sharing her pregnancy at the 2025 Fashion Awards in London Dec. 1.
During the event, the 43-year-old—who is also mom to daughter Marlowe, 13, with ex Tom Sturridge as well as a 23-month-old daughter with Oli, 28—definitely wasn’t hiding her baby joy, arriving in a sheer white Givenchy gown that put her growing bump on full display.
As Marlowe gears up to be a big sister once again, the American Sniper previously admitted her teen’s role as an elder sibling took some easing into.
“Initially, it was a lot for her,” Sienna told E! News in June 2024, “and now she is in heaven.”
The sisterly affection seemed to be mutual, as Sienna added that her toddler was “already idolizing” Marlowe and “beaming every time she sees her.”
