Wunmi Mosaku, known for her role as Annie in Sinners, is sharing pregnancy advice with her costar Hailee Steinfeld, who also stars in the series as Mary. Both actresses, currently expecting, are bonding as they navigate the challenges and joys of pregnancy together. This connection emerges as Mosaku prepares for her second child, while Steinfeld anticipates becoming a first-time mother with her husband, Josh Allen.
Mosaku, the 39-year-old Loki actress and mother of a toddler daughter, announced her pregnancy at the 2026 Golden Globe Awards, roughly a month after Steinfeld, 29, revealed her own pregnancy news. Their shared experience has sparked meaningful conversations, as Mosaku imparts insights gained from her earlier journey into motherhood.
Advice from an Experienced Mother to a First-Time Mom
Speaking to Entertainment Tonight during the 2026 National Board of Review Awards Gala, Mosaku explained the guidance she gave to Steinfeld as the younger actress approaches motherhood. She stressed the importance of enjoying the fleeting moments despite the physical hardships that pregnancy brings.
“I mean, my advice generally is be careful which advice you take, but I really wanted her to enjoy the moment,”
Mosaku said.
“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.’”
Reacting to a Viral Meme About Their Characters
Mosaku also addressed a popular meme circulating online that jokes about the pregnancies of their characters in the vampire thriller Sinners. Fans humorously suggested that Michael B. Jordan’s characters, Smoke and Stack, were responsible for the on-screen pregnancies of Annie and Mary.
“We had a feeling that might happen,”
Mosaku admitted.
“And you know, the internet never fails.”
Celebrating Motherhood in Style and Spirit
On the red carpet, Mosaku proudly revealed her baby bump in a bright yellow custom gown designed by Matthew Reisman. The color symbolizes the Yoruba phrase Iya ni Wúrà, meaning “mother is golden,” which holds deep cultural significance for her. Mosaku expressed certainty about her choice, stating,
“I knew it was the right dress and the right moment.”
Coinciding with her appearance at the Golden Globes, a personal essay by Mosaku was published in Vogue, in which she shared the emotional reasons behind publicly announcing her pregnancy. She described the experience as sacred yet conflicted, emphasizing the tension she feels between joy and caution.
“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.”
She also spoke candidly about the intrusive speculation that often accompanies a celebrity’s pregnancy, acknowledging the public curiosity about her appearance and choices.
“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?”
“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.”
The Complex Reality of Pregnancy for Black Mothers
Mosaku reflected on her experience navigating pregnancy as a Black woman, highlighting the mix of joy and anxiety that often accompanies this phase due to medical risks and societal challenges. She revealed how her first pregnancy was overshadowed by fears about her and her child’s safety until receiving reassurance from her healthcare provider.
“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 poignantly.
Balancing Motherhood, Career, and New Ventures
While preparing to welcome her second child, Mosaku remains proud of the success of Sinners and continues to balance her professional life with her role as a mother. She shared moments of chasing after her toddler, which she finds a welcome distraction amidst the demands 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,”
Mosaku 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.”
This new venture reflects Mosaku’s determination to support women throughout motherhood by providing thoughtfully designed clothing that respects their changing bodies and experiences.
Looking Ahead: The Shared Journeys of Mosaku and Steinfeld
As Wunmi Mosaku and Hailee Steinfeld continue to embrace the transformations of pregnancy and motherhood, their bond grows stronger, grounded in personal experience and mutual support. Mosaku’s advice and advocacy highlight the importance of joy, rest, and self-care during this intense time, while her reflections expose the unique challenges faced by Black mothers. Their stories, both on and off screen, will likely inspire others navigating the complexities of pregnancy and parenthood.
