In a 2024 interview with Harper’s Bazaar, Sienna revealed she met Green at a Halloween party, although she admitted “didn’t expect” it to be another serious. “And then quite quickly, I fell in love,” she told the outlet. “I wasn’t like, ‘I’m gonna get a younger boyfriend.’ It was more, ‘F—! Why are you young? That’s so annoying.’ “
In January 2024, People reported that the couple welcomed their first child together, a girl. In December 2025, Miller announced that she and Green were expecting their second child who she revealed was born in the Spring.

The “Layer Cake” actress previously dated Tom Sturridge from 2011 to 2015, with whom she shares her 11-year-old daughter, Marlowe. She was previously in a highly publicized relationship with Jude Law, which ended in a huge cheating scandal.

Sienna Miller Defends Age Gap With Oli Green
GettyIn November 2022, Sienna Miller opened up to British Vogue about her the 15-year age gap between her and Green.
“There’s a misogyny that is ingrained in men of my age and older that I don’t see in [the] generation below,” the “Jack Ryan: Ghost War” star said.
Sienna also told the outlet that she hoped to be married by the time she reached 40 after spending her 30s dating. “I’d invested what felt like the important years in something that was just a bucket with a hole in it of a person,” she said. “I wasted time. And I felt like time was really my currency.”
She also told Harper’s Bazaar about how values differ with the age gap. “There is a difference in the way that generation of men respect women. It’s specific to him, he is very wise and well-adjusted, but I do believe it’s also that generation. They have grown up with a slightly more level playing field. I see it in his female friends as well as in the men,” Miller told the magazine.
