Jesy Nelson and Fiance Split Just Weeks After Twins’ Devastating Diagnosis

Jesy Nelson and Fiance Split Following Twins’ Spinal Muscular Atrophy Diagnosis

Jesy Nelson, the former Little Mix star, and her fiancé Zion Foster have reportedly ended their relationship just weeks after receiving the heartbreaking diagnosis of their twin daughters. The couple, who welcomed twins Ocean Jade and Story Monroe in May last year, have been facing immense challenges since the birth of their daughters, who were diagnosed with Spinal Muscular Atrophy (SMA) Type 1—a rare and severe genetic disorder.

Jesy, 34, and Zion, 27, began their relationship in 2022 after years of friendship. Their romance was marked by ups and downs, including several breakups and reconciliations. However, things appeared to stabilize in 2025 when they announced they were expecting twins. The joyous news was soon overshadowed by complications during pregnancy and after birth, including Jesy’s hospitalization due to Twin-to-Twin Transfusion Syndrome (TTTS), a serious condition that affected the twins in utero.

The Difficult Journey of Jesy Nelson and Her Twins

The twins were born prematurely on May 15 and spent several weeks in intensive care. Jesy documented much of their journey through a Prime Video docuseries, offering fans an intimate look at the struggles and triumphs of new parenthood under extraordinary circumstances. However, the most devastating news came months later when the twins were diagnosed with SMA Type 1.

SMA is a genetic condition that progressively weakens muscles throughout the body, affecting movement, breathing, and swallowing. Jesy shared her emotional response to the diagnosis on social media, revealing how the news shattered her world and forced her to grieve the life she had envisioned for her children. She described the overwhelming responsibility of becoming a full-time carer, managing breathing machines and other medical equipment that no parent should have to handle.

Jesy explained that the initial signs of SMA were subtle, with her mother noticing that the twins were not moving their legs as expected. Despite reassurances from healthcare professionals that the twins’ premature birth could explain developmental delays, Jesy persisted in seeking answers when feeding difficulties arose. The diagnosis of SMA Type 1 was confirmed after months of medical appointments and tests.

Following the diagnosis, Jesy and Zion’s relationship reportedly came under strain. Sources close to the couple have revealed that they have decided to separate but remain committed to co-parenting their daughters with love and unity. A source told The Sun, “She and Zion remain friends and are fully focused on their daughters. They are fully united in co-parenting. Their priority continues to be the well-being of their daughters.”

The split comes just months after the couple announced their engagement in September, sharing the joyous news with fans on social media. Despite the end of their romantic relationship, both Jesy and Zion are determined to provide a supportive and nurturing environment for Ocean Jade and Story Monroe.

Zion has also been vocal about the challenges they face, sharing a heartfelt poem on Instagram that highlighted the absence of newborn screening for SMA and the emotional toll of the diagnosis. He expressed his hope and determination to love and accept their daughters unconditionally, regardless of the obstacles ahead.

Understanding Spinal Muscular Atrophy (SMA) and Its Impact on Families

Spinal Muscular Atrophy is a genetic disorder characterized by the progressive loss of motor neurons, leading to muscle wasting and weakness. SMA Type 1, the most severe form, typically manifests in infancy and can severely impact a child’s ability to move, breathe, and swallow. Without timely treatment, the life expectancy for children with SMA Type 1 is often less than two years.

The diagnosis of SMA is a devastating blow for any family, and Jesy Nelson’s openness about her daughters’ condition has brought much-needed awareness to the disease. Her willingness to share the raw and emotional reality of caring for children with SMA has resonated with many and highlighted the importance of early diagnosis and support.
