Sienna Miller Engaged to Oli Green After Welcoming Their 2nd Baby

by

Sienna Millerand Oli Green are taking a major step in their romance.

I’m so thrilled to share some wonderful news! The incredibly talented actress known for her role in American Sniper and the handsome actor you know from The Crown are engaged! It’s such a happy time for them, especially after welcoming their second baby. It’s lovely to see their relationship blossom like this!

Rumors started flying that Miller is engaged after she was seen in Spain on June 4th with a large diamond ring on her ring finger. TopMob News has now confirmed that the ring is an engagement ring.

While out and about, Green made sure her ring was visible. She paired it with a casual outfit of sunglasses, jeans, and a jacket. The 44-year-old, who has a 13-year-old daughter named Marlowe with her ex-partner Tom Sturridge, and two other young children, walked with her hands positioned to highlight the ring.

Miller and Green, who began dating in 2022, recently got engaged—a big step for the couple. They also welcomed their second child last month, making it a wonderful year for them.

 “It’s happened,” Miller quipped to TopMob News at the time. “I have a tiny baby next door.”

The actress, known for her role in Jack Ryan, shared that she’s exhausted but overjoyed with her new baby.

Miller recently talked about how she’s managing life with three children, and revealed which one has been the most challenging to raise lately.

She jokingly told an audience on The Tonight Show on May 14th that she used to think parenting a teenager would be the biggest challenge, but a recent transatlantic flight with her toddler and newborn proved her wrong. She described the flight as a complete disaster, saying the toddler is far more difficult to handle than a teenager – and there’s no reasoning with him.

Indeed, Miller admitted that flying with her kids was a particular struggle. 

You know, traveling with a little one can be tough. I remember one flight so vividly – the looks you get when your baby is having a meltdown, and honestly, I was right there with them, trying to soothe her. It all just hit me when I finally got to immigration, and I completely fell apart. It’s a reminder that even though we prepare, sometimes those moments just overwhelm you, and that’s okay. It’s a vulnerable experience, and it’s important to acknowledge that.

Green is consistently supportive of her. Miller has even said that her relationship with the 27-year-old has made her reconsider her previous views on dating younger men.

In a 2024 interview with Harper’s Bazaar, she noted a difference in how men from different generations treat women. She believes this particular man is respectful because he’s wise and emotionally mature, but also attributes it to his generation having grown up with more equal opportunities for both genders.
