NEED TO KNOW
- Sinners actress Wunmi Mosaku is bonding with her costar Hailee Steinfeld amid their pregnancies.
- The actress shared advice with Steinfeld regarding her transition into motherhood.
- Mosaku is already a mother to a daughter.
Wunmi Mosaku, known for her role in Sinners, is connecting with her costar, Hailee Steinfeld, as both actresses navigate their pregnancies.
At the 2026 Golden Globe Awards, Mosaku, 39, announced her pregnancy on the red carpet, just weeks after Steinfeld, 29, revealed she is expecting her first child with husband Josh Allen. Mosaku plays Annie in Sinners, while Steinfeld portrays Mary in the same series.
In a conversation with Entertainment Tonight at the 2026 National Board of Review Awards Gala, Mosaku discussed the advice she offered Steinfeld as she approaches motherhood.
“My advice generally is be careful which advice you take, but I really wanted her to enjoy the moment,” Mosaku expressed. “It’s hard. It’s a lot on the body, and so like rest as much as you can and show up when you can. But enjoy it because you’ll look back on this moment and think, ‘Wow, I did it with you inside me. I did it.'”

During the discussion, Mosaku also touched on a meme stemming from their on-screen characters in the popular vampire thriller, which humorously implied that their pregnancies resulted from their partners’ roles in the film.
“We had a feeling that might happen,” Mosaku noted. “And you know, the internet never fails.”
Mosaku showcased her baby bump in a striking yellow gown by Matthew Reisman, which she revealed symbolized the Yoruba phrase, “Iya ni Wúrà,” meaning “mother is golden.” She reflected, “I knew it was the right dress and the right moment.”
Coinciding with her red carpet announcement, Vogue published a personal essay by Mosaku outlining why she chose to share her pregnancy news at the Golden 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, emphasizing the importance of the moment as she moves through awards season with her growing bump.
“I’ve been advised to get ahead of speculation and questions… 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,” she added. “So, I’ve decided to stop trying to camouflage my bump today at the Golden Globes so I can truly enjoy and embrace the moment fully together with my baby.”

In reflecting on her experience as a Black mother, Mosaku noted, “For many, peace comes once a baby is placed on their chest. For Black mothers, the path to peace is rarely that simple.” She highlighted the complexities and challenges of pregnancy, particularly within the context of the statistics surrounding Black maternal health.
“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 prepares to welcome her second child, Mosaku is finding joy in her successful role in Sinners, while also managing the energetic demands of her toddler.
Additionally, Mosaku is launching a new clothing line for mothers called Iyadé, which translates to “mother has arrived” in Yoruba. She remarked that the line is inspired by her own experiences, aiming to provide comfort and dignity for mothers in transition.
