Sienna Miller Is Engaged to Oli Green, and the Baby Got There First
The diamond did most of the talking on that Barcelona sidewalk.
Sienna Miller is engaged to Oli Green, the model and “The Crown” actor 15 years her junior.
The first sign came on a Barcelona sidewalk June 4, when Miller stepped out with a diamond on her left hand and her newborn strapped to her chest. E! News confirmed days later that it was an engagement ring.
Miller and Green met at a party in 2021 and went public the following year. She returned to Instagram in March, her first post in eight years, to announce the pregnancy.
The couple welcomed their second child together May 11, weeks before the engagement news. Miller has answered for the age gap before. “There is a difference in the way that generation of men respect women,” she told Harper’s Bazaar in 2024.
#SiennaMiller has added a new agent to her mission. The G.I. Joe actress revealed she welcomed her third baby, and second with boyfriend OliGreen. “It’s happened,” Sienna told E! News’ Will Marfuggi in an exclusive interview. “I have a tiny baby next door.” Indeed, the American Sniper actress—who is mom to Marlowe, 13, with ex Tom Sturridge as well as another 2-year-old daughter whose name has not been shared publicly with Oli—admitted it’s been an adjustment to becoming a blended family of five after she and Oli announced her pregnancy late last year. “It feels like stringing sentences together is a bit challenging,” she joked. “I’m on very little sleep but I’m madly in love with my baby.” Of course, being a mom of three isn’t the only new chapter Sienna is embarking on. After all, she is set to star in Tom Clancy’s Jack Ryan: Ghost War later this month, which is a follow-up to the television series that ended in 2023. “I loved it,” the 44-year-old said of signing on to play M16 officer Emma Marlowe opposite titular star John Krasinski in the movie. “I haven’t done anything really like this before and to play someone who is incredibly unapologetic, incredibly tough and bold and brave and pretty funny and dry and very cool—it was thrilling.” And Sienna’s costar couldn’t help but heap praise on her ability to dive headfirst into the world he’s been living in since 2018. “I don’t know if this movie happens if Sienna said no,” John mused to E!, “because we had written the part for her and I just knew we’d be so lucky to not only get who I think is one of the best actors working but I didn’t know she was one of the funniest people on planet Earth.” As he put it, “To be in these pressure cooker situations doing stunts but wiping tears of laughter away right before you do them was extremely helpful.”
She is parenting three now: Marlowe, 13, with ex Tom Sturridge, plus a toddler and a newborn with Green. For what it’s worth, she says the baby already outranks the teenager.
