Wunmi Mosaku Shares Wise Advice with Pregnant Co-Star Hailee Steinfeld

In the glittering world of Hollywood, where spotlights often overshadow personal milestones, two rising stars are turning heads for all the right reasons. Wunmi Mosaku, the acclaimed British-Nigerian actress known for her roles in Loki and Lovecraft Country, has revealed the intimate parenting advice she offered her Sinners co-star Hailee Steinfeld as both navigate the joys and challenges of pregnancy. This story of sisterhood and impending motherhood comes at a pivotal time, blending professional triumphs with personal revelations during the bustling 2026 awards season.

The Pregnancy Announcements That Captivated Fans

Wunmi Mosaku's journey into her second pregnancy became public knowledge on the red carpet at the 2026 Golden Globe Awards, held at The Beverly Hilton in Beverly Hills. The 39-year-old actress, radiant in a custom Matthew Reisman gown in a vibrant sunshine yellow, debuted her growing baby bump with poise and pride. The color choice was no accident; Mosaku explained to Vogue that it symbolized the Yoruba phrase 'Iya ni Wúrà,' translating to 'mother is golden.' This cultural nod highlighted her heritage and the sacredness of her experience.

Just weeks earlier, in December 2025, Hailee Steinfeld, 29, announced her first pregnancy with husband and NFL quarterback Josh Allen. The Hawkeye alum's news sent waves through social media, with fans celebrating the couple's expanding family. In Sinners, a gripping vampire thriller directed by Ryan Coogler and starring Michael B. Jordan, Mosaku portrays Annie, while Steinfeld plays Mary—two women entangled in a tale of supernatural suspense and survival. Their on-screen chemistry has evidently spilled over into real life, fostering a bond deepened by shared maternal anticipation.

Mosaku's Reflections on Sharing Her 'Sacred News'

In a poignant essay published by Vogue coinciding with her Globes appearance, Mosaku delved into the vulnerability of going public with her pregnancy. '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. As awards season ramps up, with Sinners earning buzz for its innovative storytelling and stellar ensemble, Mosaku acknowledged the inevitability of her bump stealing the show. Her decision to embrace it publicly underscores a modern shift in celebrity culture, where authenticity trumps perfection.

Mosaku, already a mother to a young daughter from a previous relationship, brings a seasoned perspective to this chapter. Her first foray into parenthood, she has shared in past interviews, was transformative, blending the demands of a thriving career with the profound responsibilities of raising a child. Now, expecting her second, she approaches it with a mix of excitement and pragmatism.

Heartfelt Advice from One Mom to Another

During an exclusive chat with Entertainment Tonight at the 2026 National Board of Review Awards Gala, Mosaku opened up about the guidance she imparted to Steinfeld. As a first-time mom-to-be, Steinfeld is stepping into uncharted territory, and Mosaku's words were a beacon of wisdom. 'My advice generally is be careful which advice you take, but I really wanted her to enjoy the moment,' Mosaku shared. She emphasized the physical toll of pregnancy—'It's hard. It's a lot on the body'—urging rest and presence where possible.

Yet, Mosaku's message transcended practicality, touching on the magic of the experience. 'Enjoy it because you'll look back on this moment and be like, "Wow, I did it with you inside me. I did it,"' she advised. This encouragement resonates deeply in an industry that often pressures women to compartmentalize their lives. For Steinfeld, balancing her roles in film, music, and now family, such counsel from a peer like Mosaku is invaluable. It's a reminder that motherhood, even in Hollywood's high-stakes environment, can be a source of empowerment rather than a hindrance.

Bonding Amid the Buzz of 'Sinners'

Their connection isn't just personal; it's rooted in the collaborative spirit of Sinners. The film, which explores themes of legacy, identity, and otherworldly threats in a 1930s Mississippi setting, has positioned Mosaku and Steinfeld as breakout forces. Co-starring Delroy Lindo and Miles Caton, the project marks a significant milestone for both actresses. Mosaku's performance as Annie, a resilient figure in a world of darkness, mirrors her real-life strength as she prepares for family expansion.

Off-screen, their pregnancies have sparked a delightful online phenomenon. Fans have created memes joking that the duo's real-life bumps are a nod to their characters' entanglements with Jordan's dual roles as Smoke and Stack. Mosaku laughed it off during her ET interview: 'We had a feeling that might happen. And you know, the internet never fails.' This lighthearted viral moment highlights how Sinners is resonating beyond theaters, blending horror with humor in pop culture.

Broader Implications for Hollywood Motherhood

Mosaku and Steinfeld's stories reflect evolving narratives around women in entertainment. Historically, pregnancies have sidelined careers, but today's landscape—bolstered by advocates like Mosaku—celebrates them. Mosaku's essay touches on this, noting how she'll navigate awards circuits with her 'ever-growing bump,' turning potential scrutiny into a statement of joy.

For Steinfeld, whose marriage to Allen in 2025 was a fairy-tale affair, this pregnancy caps a year of personal highs. Allen, the Buffalo Bills star, has been vocal about his excitement, sharing glimpses of their life together on social media. The couple's journey from on-field victories to family beginnings adds a relatable layer to Steinfeld's star power.

As Sinners gears up for wider release, expect more from this dynamic pair. Mosaku's advice not only aids Steinfeld but inspires fans worldwide, proving that even in Tinseltown, vulnerability forges the strongest connections. With awards on the horizon and babies on the way, 2026 promises to be a golden year for these luminous talents.
