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

by

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. 

Sienna revealed in an exclusive interview with Will Marfuggi of TopMob News that a new baby has arrived next door to her. “It’s happened,” she said. “I have a tiny baby next door.”

As a mom to thirteen-year-old Marlowe (with my ex, Tom Sturridge) and a little one with Oli, plus our newest addition who’s just two, let me tell you, blending a family of five has been a real adjustment! It’s been a beautiful, sometimes chaotic, journey since we announced our pregnancy last year, figuring out this new dynamic and making sure everyone feels loved and connected.

She laughed, saying it felt hard to get her thoughts into words. She explained she was running on very little sleep, but completely overjoyed with her new baby.

Okay, so everyone’s talking about Sienna becoming a mom to three, which is AMAZING, but honestly? I’m losing it over the fact that she’s going to be in Tom Clancy’s Jack Ryan: Ghost War! I was seriously bummed when the original Jack Ryan series ended in 2023, and now this?! It’s like, motherhood AND action hero – can she be any more perfect?! I’ve already marked my calendar for when it comes out, I’m so excited!

Oh my gosh, I’m still buzzing about landing the role! Seriously, playing Emma Marlowe, the M16 officer alongside John Krasinski? It’s a dream come true! I’ve never gotten to play anyone like her before – she’s just…amazing. Totally fearless, doesn’t apologize for anything, and she’s so tough and brave. But the best part? She’s hilarious! That dry wit? So cool. It was honestly the most thrilling experience of my career!

Sienna’s fellow actor was quick to commend her for fully immersing herself in the world he’s known since 2018.

Honestly, I don’t think this movie would have happened if Sienna hadn’t signed on. John told TopMob that the role was practically written for her, and he really believed she was one of the best actresses around. But he was completely blown away by how funny she was – he said he had no idea she was that funny, and it totally elevated the whole project.

He explained that being in high-pressure, challenging situations – and being able to laugh right before tackling them – was surprisingly beneficial.

However, Sienna found that not everyone appreciated the gesture. Although she named a character after her thirteen-year-old daughter, she confessed that her daughter had absolutely no interest in her work.

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

She hoped calling me ‘Agent Marlowe’ would get her attention, and maybe finally convince her to watch one of my movies, she explained.
