Actress Wunmi Mosaku is offering pregnancy advice to her Sinners co-star Hailee Steinfeld as both actresses navigate their pregnancies in 2026. Mosaku, 39, who is already a mother to a daughter, announced she is expecting her second child at the Golden Globe Awards. Steinfeld, 29, revealed she is pregnant with her first baby alongside her husband Josh Allen nearly a month earlier.
The two stars continue to bond as they prepare for motherhood while working together on the vampire thriller series Sinners, with Mosaku sharing helpful guidance during an interview at the 2026 National Board of Review Awards Gala.
Advice from an Experienced Mother to a First-Time Mom
As a seasoned mom, Mosaku advised Steinfeld to savor the experience despite its difficulties. She said,
I mean, my advice generally is be careful which advice you take, but I really wanted her to enjoy the moment,
Wunmi Mosaku 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.’
Reacting to Fan Theories About Their Characters
Mosaku also addressed a meme circulating online that humorously links the pregnancies of their characters, Annie and Mary, to the fictional fathers Smoke and Stack, played by Michael B. Jordan. She acknowledged the joke with a smile, saying,
We had a feeling that might happen,
and added,
And you know, the internet never fails.
Mosaku’s Meaningful Red Carpet Appearance and Personal Essay
During the Golden Globe Awards, Mosaku made a striking entrance in a custom sunshine yellow gown designed by Matthew Reisman. The color signified the Yoruba phrase Iya ni Wúrà, meaning “mother is golden.” Reflecting on the moment, Mosaku expressed,
I knew it was the right dress and the right moment.
At the same time as the event, Vogue published a personal essay Mosaku wrote about choosing to go public with her pregnancy at such a high-profile occasion. She explained,
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,
and further added,
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.
Mosaku addressed the early speculation that followed her gown choice and appearance:
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 said,
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.
Pregnancy Reflections and Black Maternal Health Awareness
Mosaku also spoke about the unique challenges faced by Black mothers during pregnancy. She shared,
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.
Continuing, she emphasized the emotional complexity, stating,
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,
highlighting concerns that persist within her community despite the joy of motherhood.
Balancing Motherhood, Career, and New Endeavors
While preparing for her second child, Mosaku is also celebrating the success of Sinners and managing life with her toddler. She described this phase as,
chasing after my toddler, a welcomed distraction from the business of work.
Alongside acting, Mosaku is channeling her experiences into launching a new clothing line for mothers called Iyadé, meaning “mother has arrived” in Yoruba. She explained,
I’m also pouring my heart into something new—a clothing line for mothers called Iyadé—which means ‘mother has arrived’ in Yoruba,
adding,
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.
Looking Ahead to Motherhood and Career Growth
As Wunmi Mosaku and Hailee Steinfeld each prepare to welcome new additions to their families, their shared journey highlights both the joys and complexities of pregnancy and motherhood. Mosaku’s insights and support offer valuable perspective to Steinfeld and others facing similar experiences in the public eye. Meanwhile, Mosaku’s initiative with Iyadé underscores the importance of representation and care for mothers at every stage, promising continued advocacy and creativity inspired by motherhood’s challenges and triumphs.
