Sienna Miller and Boyfriend Oli Green’s Relationship Timeline

Sienna Miller met actor Oli Green at a Halloween party thrown by a mutual friend, but it wasn’t exactly love at first sight.

“I was like, ‘This is absurd. This will not go anywhere,’” she told British Vogue in December 2023. “He worked hard to persuade me to go out for a drink with him.”

Miller previously dated Jude Law on and off from 2004 to 2011. She moved on with Tom Sturridge, whom she dated from 2011 to 2015. The pair welcomed daughter Marlowe in July 2012.

After Miller connected with Green, Emily Blunt tagged along for one of their New York City dates in early 2022. Blunt told British Vogue that she sees “so much of” her longtime friend in Green, especially “that free-spirited, curious, guileless thing that he has.”
