Reveal Sienna Miller's Baby Bump: Why Her Pregnancy at 43 Is Driving Important Conversations

Zosio StaffDecember 03, 2025...

The actress hit the red carpet Monday night, and her see-through white gown didn't leave much to the imagination-including that baby bump everyone's been talking about. But it's what she's said about judgment and double standards that really deserves your attention.

Let's be real: when a 43-year-old Hollywood actress shows up pregnant to the Met Gala, the people have thoughts. And Sienna Miller? She's already heard it all-and she's not having it.

On Monday night at London's Royal Albert Hall, Miller stole the Fashion Awards show in a stunning see-through white gown that showcased her pregnancy beautifully. Hand-in-hand with her partner, 28-year-old actor Oli Green, she was glowing, confident, and utterly unbothered by the inevitable commentary her announcement would incite.

This will be Miller's third child—her second with Green, joining their nearly two-year-old daughter. She is also mom to a 12-year-old daughter, Marlowe, from her prior relationship with actor Tom Sturridge.

Why This Announcement Matters More Than You Think

Here's where it gets interesting: Miller hasn't just announced her pregnancy—she's actively pushed back against the societal judgment that comes with it.

She has called out in the past the criticism she has had for having children in her 40s, pointing out the double standard women have to endure that men don't. She's spoken on the "misogynistic" narrative surrounding the 15-year gap between her and Green, pointing out that when guys older date younger women, it barely registers-but flip those genders and now everyone's got an opinion.

Quick question for you: Why do you think society treats age gaps differently depending on who's older-the man or the woman? Drop your thoughts in the comments.

The Numbers Tell a Story

According to statistics from healthcare bodies such as the CDC and NHS, more women are choosing to have children later in life than at any other time in history. Within the UK alone, births for women over 40 have more than doubled over the last two decades. Yet the stigma remains, with terms like "geriatric pregnancy" still in common medical usage-a label that feels less clinical and more insulting.

Miller represents a growing trend of women rewriting the rules about when and how to build families. Whether driven by career priorities, finding the right partner later in life, or simply personal choice, these women challenge outdated assumptions about maternal age.

The Career vs. Baby Timeline Debate

Miller's career is a perfect case study: Rising to fame alongside Daniel Craig in films such as "Layer Cake" (2004) and again with Bradley Cooper in "Burnt" (2015), she's built up a sturdy acting resume over two decades. Not unlike many women in entertainment, the demands of her career do not give way easily to family planning.

Hollywood has long been ruthless with actresses taking time off for motherhood, especially in their so-called "prime." And many women within the industry have spoken to feeling forced to choose between one's career momentum and starting families. Miller's choice to have children later-when she's more established and, presumably, has more control over her career-reflects a strategic decision many professional women make.

Let's Talk About That Age Gap

Their 15-year age gap has generated its share of headlines, but as Miller has pointed out, the reaction would be dramatically different if she were a 43-year-old man with a 28-year-old partner. That double standard isn't just annoying—it's revealing about how society views women's agency, desirability, and life choices.

Try this as a thought experiment: Name five male celebrities over 40 who've dated or married women 15+ years younger. Easy, right? Now name five women in the reverse situation. Much harder, isn't it? And when you do find examples, notice how much more scrutiny they face.

What The Medical Community Says

Organizations such as the American College of Obstetricians and Gynecologists recognize that while pregnancies after age 40 do carry some increased risks, including increased rates of gestational diabetes and chromosomal abnormalities, many pregnancies and babies in this age range are perfectly healthy. Advances in prenatal care, genetic testing, and medical monitoring have made later stage pregnancies safer than ever.

The key word there is "risk," not "impossibility." Yet the conversation around older mothers often feels more judgmental than medical, more about societal discomfort than actual health concerns.

The Bigger Picture

Miller's red carpet appearance isn't just celebrity baby news—it's part of a larger cultural conversation about women's choices regarding reproduction, ageism, and the consistent double standards governing how we judge women versus men.

When we cheer on male actors for becoming fathers in their 50s, 60s, and even 70s, but raise eyebrows when women have children in their 40s, we betray our bias. When we question age gaps only in the cases where the woman is older, we are reinforcing sexist assumptions that women's value is bound to their youth.

Miller seems to understand this completely. Showing up visibly pregnant, aglow, and with her younger partner in tow, she refuses to hide or apologize. She's living her life on her own terms and daring anyone to have a problem with it.

So, what do you think?

We want to hear from you:

Do you believe society is harder on older mothers than on older fathers?

Of course, the double standard exists.

Somewhat, but it is improving.

Not really, both face equal scrutiny.

Not quite sure


And the big question: Should women's reproductive choices even be up for public debate? Or is it time we collectively mind our own business about who has babies, when, and with whom?

Share your thoughts in the comments—but let's keep in mind that this is about prevailing societal attitudes, not Miller's personal medical situation, which is nobody's business but her own.

The Bottom Line

Sienna Miller is 43, pregnant, in love with a 28-year-old man and stepping onto red carpets in see-through gowns, her baby bump on view for all to see. Some people are going to have opinions about all of that. But increasingly, the response seems to be: So what?

Family building looks different for everyone. Career timelines don't follow a universal script. Love doesn't consult an age calculator before it happens. And women-shock of all shocks-are capable of making informed decisions about their own bodies and lives.


Miller's pregnancy announcement is just that: an announcement. But the conversations it's sparking about age, judgment, and double standards? Those are worth having. Congratulations, Miller and Green. And to the rest of you? Perhaps it's time to update our attitudes about women's choices to reflect which century we're really living in. What is your opinion on it? Are we making progress in this issue or is judgment still too critical? Comment below.
