Sienna Miller on falling in love with Oli Green: "Why are you young? That's so annoying"

The couple welcomed their first child together earlier this year.

Sienna Miller is sharing how she "fell in love quickly" with her boyfriend, Oli Green.

In an interview with Harper's Bazaar published on Tuesday, June 11, the actress revealed that their relationship began after meeting at a Halloween party and was something she "didn't expect" to take "seriously."

"And then quite quickly, I fell in love. I wasn’t like, 'I’m gonna get a younger boyfriend.' It was more, 'F--k! Why are you young? That's so annoying,'" she said.

The actress described her boyfriend as someone who is "well-adjusted."

"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," said Miller. "I see it in his female friends as well as in the men."

The actress continued that as she's grown older, she's learned from "people who are younger about how clear they are in their boundaries, having that self-assuredness and self-advocacy, having 'no' in the repertoire in a way that we just weren’t encouraged to have."

The couple, who made their red carpet debut at the Vanity Fair Oscar Party in March 2022, welcomed their first child together earlier this year. Miller also has an 11-year-old daughter, Marlowe, with her ex, Tom Sturridge.
