Wunmi Mosaku just told the world she had a baby, and she did it on her own terms.

The Sinners actor appears on the cover of British Vogue's October issue with both her children, a 10-week-old son and a daughter who's nearly three. It's the first confirmation of the birth, and it lands months after Mosaku spent an entire awards season visibly pregnant without ever making a formal statement about it.

She wasn't hiding, exactly. Mosaku walked the Golden Globes red carpet in January in a custom yellow gown that made no attempt to disguise her bump. But the actual announcement came the same month, in a Vogue essay, where she explained why she'd resisted talking about it at all. "In my Nigerian culture, we don't really announce this kind of news," she wrote then. "It's meant to be protected."

In the new cover story, Mosaku calls last season "the most inclusive red carpet run I'd ever had," crediting designers who dressed her growing body without a fight. She's hoping that doesn't disappear once the bump does. "I really hope designers remain equally excited about dressing regular curves, not just pregnancy bumps," she said, adding she's nervous about going back to sample sizes and paying for her own tailoring.

It wasn't all glamour. Mosaku admitted to "struggling with pain, stretching ligaments and exhaustion" through the entire Sinners campaign, which ended with her nominated for the supporting actress Oscar. The film itself had a big night at the Academy Awards, with wins for director Ryan Coogler, star Michael B. Jordan, cinematographer Autumn Durald Arkapaw and composer Ludwig Göransson.

Mosaku, married to talent agent Tash Moseley, also used the interview to talk about the specific anxiety of being pregnant as a Black woman. "You're not just worrying about whether your baby will be okay," she wrote earlier this year. "You're praying you will be too. Holding joy and fear at the same time is not abstract. It's rooted in lived experience, medical bias, and real statistics."

That experience is feeding directly into her next project outside acting. Mosaku is launching a maternity wear line called Iyadé, a Yoruba word meaning "mother has arrived." Her reasoning is blunt. "I can't be the only mother who is disappointed with maternity and nursing wear," she told Vogue. "I cannot be the only person."

No launch date for Iyadé has been announced yet, and Mosaku hasn't said when she plans to be back on screen. For now, the cover is the news.
