Jesy Nelson and Fiance Zion Foster Split After Their Twins’ Shock Diagnosis – But Exes Remain ‘United as Co-Parents’
Jesy Nelson and Zion Foster’s Relationship Journey Amidst Twins’ SMA Diagnosis
Jesy Nelson, the former Little Mix star, and her fiancé Zion Foster have recently announced their split after four years together. The news comes amid the emotional and challenging journey they have faced following the diagnosis of their twin daughters with Spinal Muscular Atrophy (SMA) Type 1, a severe and life-threatening genetic condition. Despite ending their romantic relationship, Jesy and Zion have chosen to remain united as co-parents, focusing all their energy on supporting their daughters, Ocean Jade and Story Monroe.
The couple’s story began in 2022 after years of friendship blossomed into romance. In January 2025, Jesy and Zion joyfully revealed they were expecting identical twins. However, Jesy’s pregnancy was soon classified as high-risk due to a rare condition called twin-to-twin transfusion syndrome (TTTS), which affects identical twins sharing a placenta. Jesy underwent in-utero surgery and months of medical supervision before the premature birth of their daughters in May.
Shortly after birth, the twins were diagnosed with SMA Type 1, a condition that severely affects muscle strength and movement. This devastating news has profoundly impacted Jesy and Zion’s lives, but they remain steadfast in their commitment to their children’s care and future.
Understanding SMA and Its Impact on Jesy Nelson’s Family
Spinal Muscular Atrophy (SMA) is a rare genetic disorder characterized by progressive muscle weakness and loss of motor neurons. Type 1 SMA is the most severe form, often leading to significant challenges such as difficulty swallowing, breathing problems, and limited mobility. Tragically, without early intervention, the life expectancy for infants with SMA Type 1 is typically around two years.
Jesy’s twins, Ocean Jade and Story Monroe, have been diagnosed with this severe form of SMA. Their mother has shared that the girls are unlikely to walk or regain neck strength and will probably require wheelchairs. Despite this prognosis, Jesy remains hopeful, inspired by stories of children who have defied medical expectations.
The twins are currently receiving treatment at Great Ormond Street Hospital in London, including a one-time gene therapy infusion approved by the NHS. This treatment offers hope for slowing disease progression and improving quality of life.
Jesy has become a passionate advocate for SMA awareness, campaigning for the inclusion of SMA screening in the NHS newborn heel-prick test. Currently, this test screens for ten conditions but does not include SMA, which Jesy believes could prevent many children from facing severe disability if detected early.
Jesy Nelson’s Campaign to Add SMA to Newborn Screening
Following the diagnosis of her twins, Jesy Nelson has dedicated herself to raising public awareness about SMA and pushing for systemic change in newborn screening protocols. She has launched a petition urging the UK government to add a simple, non-invasive £4 blood test for SMA to the NHS newborn heel-prick test.
Jesy emphasizes that early detection is critical. If babies with SMA are diagnosed promptly, treatments like gene therapy can significantly improve outcomes and reduce the risk of lifelong disability. According to Jesy, this screening could prevent approximately 33 children each year from needing wheelchairs for life.
Jesy’s advocacy has garnered widespread support from fans and the public alike. She has shared emotional videos and appeared on television programs such as ITV’s This Morning to discuss her daughters’ health battle and the urgent need for change.
Despite the immense challenges Jesy faces as a mother of children with a severe illness, she remains optimistic and determined. She believes that with the right support and medical advances, her daughters can defy the odds and achieve milestones once thought impossible.
Co-Parenting and Moving Forward After the Split
Though Jesy Nelson and Zion Foster have ended their engagement, sources close to the couple confirm that they remain friends and are fully committed to co-parenting their daughters. Both prioritize the well-being of Ocean Jade and Story Monroe above all else.
Zion continues to support Jesy emotionally and practically, even writing a heartfelt poem dedicated to their “two little warrior girls.” Their shared focus is on providing the best care and love for their children, navigating the complexities of SMA together despite their changed relationship status.
The couple’s decision to separate reflects the immense pressure that a life-altering diagnosis can place on relationships. Experts note that parents of children with severe disabilities often experience heightened stress, which can lead to relationship breakdowns. However, Jesy and Zion’s ability to maintain a united front for their daughters is a testament to their dedication as parents.
Jesy has spoken candidly about the emotional toll of motherhood under such difficult circumstances, expressing her desire to be a mother rather than a nurse or caregiver. She acknowledges the challenges but remains focused on celebrating her children’s small victories and cherishing every moment.
Conclusion
Jesy Nelson and Zion Foster’s split following the shock diagnosis of their twins with SMA is a poignant reminder of the challenges families face when confronted with life-changing news. Yet, their story is also one of resilience, hope, and unwavering commitment to their children. Jesy’s campaign to add SMA screening to the NHS newborn heel-prick test is a crucial step toward early diagnosis and better outcomes for affected families.
