Sienna Miller is expecting her second child with boyfriend Oli Green

It didn’t even register for me that Sienna Miller has been much more “showy” about her current romance with Oli Green. I thought I would have to hunt around for photos of them together, but no, they’re not hiding at all. They started dating in early 2022, the best anyone can tell, and they seemed pretty official right away. She took him to the Met Gala, they went to Wimbledon together, they went to the theater and various premieres. And now they’re expecting! Sienna is pregnant with her second child. Her first, Marlowe, is already 10 years old.

Sienna Miller is growing her family! The American Woman actress, 41, is pregnant and expecting her second baby, she revealed as she was photographed in a bikini while vacationing in Ibiza. Miller spent time at the beach, wearing a brown two-piece that accentuated her baby bump.

Prior to her vacation in Ibiza, Miller was spotted spending time in St. Tropez with boyfriend Oli Green, 26.

Miller’s rep has not responded to PEOPLE’s request for comment.

The actress is already mom to daughter Marlowe, 10, whom she shares with Tom Sturridge.

“Miller spent time at the beach, wearing a brown two-piece that accentuated her baby bump.” I appreciate how carefully we speak and write these days, but Sienna wasn’t wearing a bikini which “accentuated” her bump. The bikini revealed her second-trimester bump and congrats to them. I’m genuinely happy for her – she’s said in previous interviews that she would have liked to have another child, but she had no idea how much work it was being a mom. From what little I know about her life, it also seems like she’s on good terms with her ex Tom Sturridge and they coparent successfully. As for Oli Green… he’s pretty young. But maybe it will work out. If it doesn’t, Sienna will be fine.

    I’m happy for Sienna and her growing family. 26 IS young but I suppose he’s had some life experiences already and has his own money.

    I’m going to say that Sienna’s 41 is a lot of other women’s 31.

      She looks great and these pics are especially flattering, but I remember watching her in “Anatomy of an Affair” and marveling at how great it is that she’s aging so naturally. To me, she looks like a 41 year old who takes great care of herself (come to think of it, she was younger than 41 in the show and she looked like a pretty woman in her late 30s-early 40s).

    Her house in AD is one of my favorites, especially the garden. I didn’t realize how close she is to my age (one year younger than me). She seems way less dramatic now than she was.

    • Kilo Tango says:

      Yeah I loved that home tour. It was a unique quirky British home and a lot of thought had gone into it.

  4. LOLA says:

    I don’t know that it’s fair to say she was “dramatic”. If you have read interviews with her in recent years, she just sounds like someone who was in love with Jude Law and has been exploited terribly by the phone hacking scandal perpetrated by the media. Yes she had an affair with a married man but she sounds pretty normal to me, for someone in the spotlight, especially.

    • Normades says:

      She was definitely not low key when she was seeing Balthazar Getty, flaunting the relationship openly on a yacht. It was messy for sure. I think she made a lot of enemies in hwood with that relationship as his wife was tight with the whole Jennifer Aniston/Jen Mayer friend group.
      Let’s also not forget she was cheating on Law with his best friend Daniel Craig. Also her feud with Kate Moss who hated her. So yea, girl was definitely a bit dramatic.

    • Digital Unicorn says:

      Yes she was a victim of phone hacking but girlfriend was very dramatic back in the day – she and her then publicist were infamous for tipping off the paps Her thirst for fame and messy relationships cost her roles, hence why she ended up disappearing off the radar for several years. She’s learned to keep her relationships it under wraps.

      Congrats to her and Oli!!

    Her boyfriend resembles Judy Law..

  6. Normades says:

    I was surprised to learn her ex Tom Sturrige is with Alexa Chung. Dude definitely likes his fashion it girls as does her ex Alex Starsagar

    I know women tend to hate her, but I like sienna. She was great in Factory Girl, her performance was so underrated. Plus I love her style. Congrats on her pregnancy.

    • Kirsten says:

      I also really like her. She’s good in so many things, and her style is always fun. Happy that she seems to be in a good place!

    • Digital Unicorn says:

      She’s a decent enough actress but I find her a bit annoying in interviews.

  8. Andrea says:

    I am 42 and cannot imagine being with much less having a baby with a 26 year old.

  9. Jaded says:

    The comments on how “I can’t imagine being this age and having a baby” are tired and super judgmental.

    • Yup, Me says:

      I have a baby at this age and tired and judgmental is all I have left.

      Doing it for the second time definitely makes things easier, but doing it with a 26 year old dude who is doing it for the first time sounds like an exercise in misery. I hope she takes that one mama’s advice and decides to be the dad role (and makes the boyfriend be the mom).
