Sienna Miller Recalled “Quickly” Falling In Love With Oli Green And Admitted It Was “Annoying” When She Found Out He Was 14 Years Younger Than Her

Since Sienna Miller and Oli Green were first linked over two years ago, there’s been a lot of chatter about their 14-year age gap.

And now, in a new interview, Sienna has shared more about the start of their relationship, explaining that she didn’t intend to end up with someone that much younger than her.

Speaking to Harper’s Bazaar UK, Sienna recalled meeting Oli at a Halloween party, where it took her a little while to consider that he could be a potential partner.

“I didn’t expect to take it seriously,” she said, “and then quite quickly, I fell in love.”

From what we know, Oli would’ve been around 24 when they met, while Sienna would’ve been 39. Speaking about their age gap, she said it wasn’t a massive appeal that Oli was younger than her but rather an annoyance.

“I wasn’t like, ‘I’m gonna get a younger boyfriend,’” she said. “It was more, ‘Fuck! Why are you young? That’s so annoying.’”

Despite this, the pair soon started dating and have been together ever since. They welcomed a daughter together late last year, and in her new interview, Sienna admitted she finds dating someone from a different generation quite soothing and enlightening.

In December 2023, Sienna told Vogue that the idea of dating Oli was initially “absurd” to her, revealing that he “worked hard to persuade [her] to go out for a drink with him” after their first meeting.

Even after Sienna agreed to go out with Oli, she was still a little unsure, so she enlisted the company of her good friend Emily Blunt, who served as her “wingwoman” on one of their earliest dates.
