Sienna Miller is glowing—and officially expecting her third child with her 15-years-younger boyfriend, Oli Green.
The Alfie and Factory Girl star, 43, revealed her pregnancy on the red carpet at the 2025 Fashion Awards in London, where she stunned in a sheer white gown that elegantly showcased her growing bump. Standing proudly beside her was Green, 28, looking dapper in a black suit as the couple smiled for cameras.
The two, who began dating in 2021, already share one daughter and have long defied Hollywood expectations about age-gap relationships.
In a recent interview with Harper’s Bazaar, Miller opened up about how the romance began—and how quickly she fell for Green despite their age difference.
“I didn’t think I’d take him seriously,” she admitted. “I wasn’t looking for a younger boyfriend—if anything, I thought, Why is he so young? It’s annoying. But I fell in love really fast.”
Miller also praised Green’s maturity and outlook on relationships: “There’s something different about how younger men respect women. He’s incredibly wise and adaptable. I think it comes from growing up in a more equal environment.”
Miller, known for her performances in The Lost City of Z and American Sniper, has led a life as eventful off-screen as on it. She was previously engaged to Jude Law in 2005 before their relationship collapsed amid his infidelity. Later, she shared a four-year relationship with Tom Sturridge, with whom she co-parents her daughter Marlowe.
Now, Miller seems to have found balance—and happiness—with Green, who’s carving out his own acting career with roles in A Good Person and the upcoming Lift.
“Sienna’s absolutely glowing,” a source tells The Daily Mail. “She’s relaxed, happy, and really embracing this new chapter.”
