Little Mix’s Jesy Nelson Splits From Fiance Amid Babies’ Muscle Disease: Report

Jesy Nelson and Zion Foster Separate Amid Twins’ SMA Diagnosis

Jesy Nelson, widely known as a former member of the British girl group Little Mix, has reportedly ended her engagement with longtime partner Zion Foster. This news comes shortly after Jesy revealed that their eight-month-old twin daughters, Story and Ocean, were diagnosed with spinal muscular atrophy (SMA) type 1, a severe genetic muscle disease. According to reports from The Sun on January 19, 2026, Jesy and Zion have decided to part ways after four years together but continue to maintain a friendly relationship to co-parent their children.

The couple’s engagement was announced in September 2025, just a few months after Jesy gave birth to their twins. The joyous occasion was soon overshadowed by the twins’ health struggles, which Jesy openly shared with her fans and followers. The diagnosis of SMA type 1 has been a devastating blow to the family, but Jesy remains hopeful and determined to fight for her daughters’ future.

Understanding Spinal Muscular Atrophy Type 1 and Its Impact

Spinal muscular atrophy (SMA) type 1 is a rare genetic disorder that affects muscle strength and movement. It is the most severe form of SMA and typically manifests in infants within the first six months of life. The disease causes progressive muscle wasting, impacting essential functions such as breathing, swallowing, and mobility.

Jesy Nelson revealed in an emotional Instagram video that her mother first noticed a lack of movement in the twins’ legs a few months ago. Initially, Jesy was reassured by healthcare professionals that the babies were healthy despite being premature. However, as feeding difficulties and muscle weakness became more apparent, further medical evaluations led to the SMA diagnosis.

The prognosis for SMA type 1 is often grim, with untreated infants facing a life expectancy of less than two years. However, advances in treatment have improved outcomes, and Jesy’s daughters have already undergone intensive therapy aimed at managing the disease.

Jesy shared, “When the doctors assessed the girls, we were told they’re probably never going to be able to walk. They’ll probably never regain any strength, so they will be disabled. The best thing we can do right now is get them treatment and just hope for the best.” Her candidness has brought awareness to this rare condition and highlighted the emotional toll it takes on families.

Jesy Nelson’s Journey Through Heartbreak and Hope

The past few months have been described by Jesy as the most heartbreaking period of her life. She expressed feelings of grief for the future she envisioned with her children, now altered by the realities of SMA. Despite this, Jesy remains grateful that her daughters are still alive and receiving treatment.

“I almost feel like I’m grieving the life I’m not going to have with my children,” Jesy said. “But at the end of the day, they’re still here and that’s the main thing. They’ve had their treatment and I truly believe my girls will defy all the odds and, with the right help, they will fight this and go on to do things that have never been done.”

Jesy’s openness about her family’s struggles has resonated with many, offering a message of resilience and hope. The singer’s commitment to her daughters’ care and her ability to maintain a positive outlook amid adversity is inspiring.
