London, January 20, 2026 — In his first public post since reports emerged of his separation from Jesy Nelson, musician Zion Foster shared an emotional and uplifting video of their eight-month-old daughter, Story Monroe Nelson-Foster, on Instagram Stories. The tender clip shows the little girl during “tummy time,” attempting to lift her head as her father gently encourages her off-camera.

“Are you gonna push up? Are you gonna push up?” Foster can be heard saying in the background, his voice full of warmth and pride. Over the video, he added the caption: “Proud of you always Story bear, my lil fighter.” The post, which quickly circulated among fans and media outlets, highlights Story’s ongoing resilience in the face of her Spinal Muscular Atrophy (SMA) Type 1 diagnosis—a condition that affects muscle strength and movement.

The timing of Foster’s update is particularly poignant, coming just days after news broke that he and Nelson, the former Little Mix star, have ended their romantic relationship after four years together. The couple, who got engaged in September 2025, welcomed twin daughters Ocean Jade and Story Monroe prematurely on May 15, 2025, following a high-risk pregnancy complicated by twin-to-twin transfusion syndrome. Sources close to the pair have emphasized that the split is amicable, with both remaining “fully united” as co-parents and prioritizing the well-being of their girls above all else.

Foster’s video serves as a quiet but powerful affirmation of that commitment. By calling Story his “lil fighter,” he echoes the language the family has used since Nelson first shared the twins’ diagnosis earlier this month. In an emotional Instagram reel, Nelson revealed that doctors had warned the girls would “probably never be able to walk” and might face lifelong dependency on wheelchairs due to the severity of SMA Type 1—the most aggressive form of the rare genetic disorder. Without early intervention, the condition can be fatal in infancy, but the twins have already received a groundbreaking one-off gene therapy infusion that halts progression in unaffected muscles.

Nelson has transformed her personal heartache into a nationwide advocacy effort, campaigning vigorously for SMA to be added to the UK’s newborn blood spot screening test (commonly known as the heel prick test). Currently, the test screens for ten conditions but not SMA, meaning many diagnoses—like her daughters’—come too late to prevent irreversible muscle loss. “I have this platform, and I almost feel like I’ve got a duty of care to raise awareness about it,” Nelson said in a recent television appearance, where she broke down discussing the “what ifs” of earlier detection. She has launched a petition and met with Health Secretary Wes Streeting, who appeared visibly moved and pledged to review genomic medicine advancements, including potential expansion of screening.

The response to Nelson’s campaign has been overwhelming, with thousands signing petitions and families affected by SMA sharing stories of how early treatment transformed outcomes. Videos contrasting children diagnosed at birth—who often walk and thrive—with those diagnosed later have gone viral, underscoring Nelson’s point that timely intervention can be life-changing. Scotland has already announced plans to include SMA in newborn screening from spring 2026, adding momentum to calls for England and Wales to follow suit.

Meanwhile, Foster’s post breaks a brief period of silence on his social media following the split reports. The 26-year-old rapper had previously been vocal in his support, praising Nelson as “the definition of a superwoman” and sharing hopeful messages about their family unity. The couple still follow each other on Instagram, and their feeds remain filled with joint milestones: engagement announcements, hospital updates from the twins’ NICU stay, and joyful first photos at home. Neither has directly addressed the breakup publicly, allowing the focus to stay on Ocean and Story.

Fans have flooded comments sections with messages of support, celebrating Foster’s dedication as a father while expressing sympathy for the family’s challenges. “This is co-parenting done right—putting the babies first,” one commenter wrote. Others praised the video for showcasing small victories in tummy time, a crucial physiotherapy exercise for SMA children to build neck and core strength despite the condition’s limitations.

The twins’ home has become a hub of medical equipment: breathing machines (particularly for nighttime use), feeding tubes, and regular physiotherapy sessions. Nelson has spoken candidly about grieving the milestones she once imagined—first steps, independent play—while finding profound gratitude in the girls’ smiles and their unbreakable twin bond. “They have each other,” she reflected, “and that’s the main thing I’m so grateful for.”

As Nelson continues her tireless awareness efforts—appearing on talk shows, sharing educational content, and pushing for policy change—Foster’s gentle update reinforces that both parents are deeply involved in the day-to-day fight. The video of Story’s determination has resonated widely, symbolizing not just one child’s strength but the quiet resolve of a family navigating extraordinary circumstances.

Upcoming projects, including Nelson’s Amazon Prime documentary series Jesy Nelson: Life After Little Mix (premiering February 13, 2026), are expected to chronicle the pregnancy, births, and early challenges, offering further insight into this deeply personal chapter. For now, the priority remains clear: giving Ocean and Story every opportunity to thrive, surrounded by love from two parents committed to their future, even as they walk separate paths romantically.

In a landscape often dominated by celebrity drama, this story stands out for its raw humanity—reminding the public of the real lives behind the headlines and the power of advocacy born from pain.
