Sienna Miller Welcomes Baby Girl With Boyfriend Oli Green

Model and American Sniper actress Sienna Miller has welcomed her second child!

The Anatomy of a Scandal actress was spotted on Wednesday on a stroll with her baby girl in a carrier and her boyfriend Oli Green in tow. The adorable trio made their way through West London bundled up with smiles on their faces. Miller has yet to share any additional details about her baby’s arrival.

Early this winter in mid-December, Miller bared her baby bump on the cover of Winter 2024 issue of Vogue. In a companion video for the interview, Miller accidentally let it slip that she was expecting a girl, who will join big sister Marlowe, 11.

Asked if Marlowe is excited to be an older sibling, Miller says, “To have a sister? A baby sister? Oh, gender reveal by accident. I’m having a baby girl.”

Miller first debuted her baby bump in a brown two-piece bikini in Ibiza, according to People. In a interview with Elle magazine Miller talked about the freedom that came with turning 40 and how entering a new decade has allowed her to escape the pressure and stress she felt from others to have a child in her 30s.

Miller stated that she was relieved to have not just left her twenties behind but her thirties, too, sharing that she felt, “pressure… [about] kids, and should I have more, and why haven’t I, and all of that, which is a really loud noise. Biology is incredibly cruel on women in that decade – that’s the headline, or it certainly was for me,” she shared.

“Then I got to 40 and I froze some eggs. Having been really focused on the need to have another baby, I’m just like, if it happens, it happens. That kind of existential threat has dissipated,” she added.

Our best to Miller on her new addition!
