Pregnant Sienna Miller Gets Real About Having a Baby Later in Life, Says She Wants to Embrace the Experience

Sienna Miller is getting candid about being pregnant at 41.

While speaking with Vogue for their December cover issue, the actress opened up about having a baby later in life, saying that she isn't exempt from her own insecurities.

"I'd love to get to a point where I didn't feel the need to make a joke of my being older and having a baby," she told the outlet. "To show I'm in on the joke."

She went on to discuss her iconic belly-baring look at Vogue World in September, saying that she was "nervous about the idea of it, but once I had it on, everything else felt boring. I was like, 'I'll have that photo for the rest of my baby's life.'"

"It's kind of fascinating to fight your own prejudice against yourself. I'm constantly doing that."

The star made waves in September as she walked the red carpet at Vogue World, wearing a white two-piece Schiaparelli ensemble. The cropped white, long-sleeve top stopped just before her bump, baring her belly.

Miller matched the piece with a voluminous white skirt and posed with her hand on her hip, accentuating her stomach.

News of the actress and fashion icon's second pregnancy — she is already mom to daughter Marlowe, 11, whom she shares with actor Tom Sturridge — first came when Miller was photographed on the beach in Ibiza, wearing a brown two-piece bikini that showed her growing bump.

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

The actress has been dating her 27-year-old boyfriend since 2022 and has previously opened up about the "pressure" to grow her family after turning 40. In a 2022 interview with Elle UK, she discussed the topic and revealed that she’d had some of her eggs frozen.

"[The] 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."
