Sienna Miller crossed paths with actor Olli Green at a Halloween celebration hosted by a mutual friend, but their initial encounter did not spark instant romance.
"I thought, 'This is ridiculous. There's no way this will lead to anything,'" she shared with British Vogue in December 2023. "He was persistent in convincing me to join him for a drink."
Miller dated Jude Law on and off from 2004 to 2011 before moving on to a relationship with Tom Sturridge, which lasted from 2011 to 2015. Their relationship resulted in the birth of their daughter, Marlowe, in July 2012.
Recently, Miller has been seen with Green, with Emily Blunt joining them for a New York City date in early 2022. Blunt shared with British Vogue that she sees many similarities between Green and Miller, particularly in their free-spirited, curious, and guileless nature.
In March 2022, the couple made their first appearance on the red carpet, and over a year later, it was revealed that Miller is expecting their first child together. Read on for a full timeline of Miller and Green's relationship.

At 40, Miller decided to freeze her eggs, revealing to Elle UK that the pressure of her biological timeline was overwhelming. "Biology is incredibly cruel on women in that decade," she expressed. "Then I got to 40 and I froze some eggs. Having been really focused on the need to have another baby, I’m just like, if it happens, it happens. That kind of existential threat has dissipated."

At 28 weeks into her pregnancy, Miller was featured on the cover of British Vogue where she candidly discussed her relationship with Green. At that time, the couple had just transitioned into their own home after residing at Green’s parents’ residence in West London.
Addressing her 14-year age gap with Green, she said, "I don't think you can legislate on matters of the heart. I certainly have never been able to."
