Sinners actress Wunmi Mosaku is bonding with her costar Hailee Steinfeld amid their pregnancies.

The Loki actress, 39, who is already a mother to a daughter, revealed that she's expecting another baby on the red carpet at the 2026 Golden Globe Awards. Mosaku, who plays Annie in Sinners, shared her exciting news nearly a month after the Hawkeye star, 29, who stars alongside her in Sinners as Mary, shared she's expecting her first baby with husband Josh Allen.

While chatting with Entertainment Tonight at the 2026 National Board of Review Awards Gala, Mosaku shared some of the advice she gave her costar as she prepares for this new journey.

"I mean, my advice generally is be careful which advice you take, but I really wanted her to enjoy the moment," she shared. "It's hard. It's a lot on the body, and so like rest as much as you can and show up when where and when you can. But, enjoy it because you'll look back on this moment be like 'wow I did it with you inside me. I did it.'"

Elsewhere in the conversation, Mosaku reacted to a popular meme circulating online based off her and Steinfeld's characters in the hit vampire thriller. The joke, started by fans of the movie, insinuated that their joint pregnancies were a result of Michael B. Jordan's characters — Smoke and Stack — getting their girlfriends pregnant.

"We had a feeling that might happen," she said. "And you know, the internet never fails."

Mosaku debuted her growing baby bump in a custom Matthew Reisman gown in a bold sunshine yellow hue, which she told Vogue is symbolic of the Yoruba phrase, "Iya ni Wúrà" which means “mother is golden." She said, "I knew it was the right dress and the right moment."

At the same time as her red carpet arrival, Vogue released a personal essay by Mosaku about why she decided to share her "beautiful, personal, sacred news" with the world at the Globes.

"Everything in me resists sharing it publicly—not because I’m not grateful or joyful, but because this feels like one of the few things that truly belongs to me," she wrote, adding, "I’ll be in the public eye for the coming weeks [during awards season] as we excitedly take our seats amongst our peers, and I will be doing it with an ever-growing bump."

"I’ve been advised to get ahead of speculation and questions. Keen eyes mean speculation has already begun. Is she pregnant? Has she gained weight? What’s with the outfit?" she shared. "Truthfully, I’d love to just show up as me—a woman who happens to be pregnant—celebrating our powerful film and our amazing team, while I protect this most sacred prayer of my life. So, I've decided to stop trying to camouflage my bump today at the Golden Globes, so me and baby can truly enjoy and embrace the moment fully together."

She also reflected on her pregnancy journey as a Black woman. "For many, peace comes once a baby is placed on their chest. For Black mothers, the path to peace is rarely that simple. Pregnancy and birth carry its own battles and terrifying statistics. I personally know that with my first child, I didn’t feel truly safe—truly able to exhale—until I received the all-clear from my OB-GYN."

"Holding joy and fear at the same time is not abstract; It’s rooted in lived experience, medical bias, and real statistics. Black maternal mortality is always on our minds," she added.

As she experiences the emotions of preparing to welcome her second child, Mosaku is basking in the success of Sinners while also spending her days "chasing after my toddler, a welcomed distraction from the business of work."

"I’m also pouring my heart into something new—a clothing line for mothers called Iyadé—which means 'mother has arrived' in Yoruba," she revealed. "Born from my own lived experience, it’s about honoring bodies in transition—offering comfort, dignity, and beauty through every phase of this journey. Centering and celebrating the creators who make life possible."
