Sienna Miller Welcomes Baby No. 3, Her 2nd With Boyfriend Oli Green

After Sienna Miller confirmed she was pregnant with her third child—her second with Oli Green—she revealed in an exclusive E! News interview that their baby has arrived, saying, “I’m madly in love.”

Sienna Miller has added a new agent to her mission. 

The G.I. Joe actress revealed she welcomed her third baby, and second with boyfriend Oli Green. 

“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.”

Unfortunately for Sienna, though, not everyone was impressed. Despite her character being named after her 13-year-old, she admitted that her eldest daughter “couldn’t be less interested in my career if I tried.”

However, she has hope once the film finally hits Prime Video May 20, she may win Marlowe over. 

“I thought people calling me ‘Agent Marlowe’ would hook her,” she explained. “So maybe she’ll finally watch a film of mine.”
