Jesy Nelson and Zion Foster Split After Twins' SMA Diagnosis
Jesy Nelson and Zion Foster Split After Twins' Diagnosis

Former Little Mix singer Jesy Nelson and her fiancé Zion Foster have reportedly called off their relationship, following the devastating diagnosis of their twin daughters with a serious genetic condition.

A Relationship Timeline Marked by Joy and Challenge

Jesy Nelson and Zion Foster began dating in January 2022. Their relationship has seen its ups and downs, including a brief separation in 2024 just before they were due to release a song together titled 'Mine'. However, they reconciled quietly in November of that same year.

The couple then shared joyful news in January 2025, announcing they were expecting twins. Jesy gave birth to daughters Ocean Jade Nelson-Foster and Story Monroe Nelson-Foster in May 2025 after what was described as a high-risk pregnancy. Their happiness continued when, just four months later in September 2025, Zion proposed and the pair announced their engagement on social media with a post calling each other "best friend".

The Heartbreaking Health Diagnosis

The couple's world changed when Jesy recently revealed that their infant daughters have been diagnosed with SMA Type 1, or spinal muscular atrophy. She described her life as having "done a 360" following the news. SMA Type 1 is a severe genetic disorder that affects muscle movement and is the most common genetic cause of death in infants.

It is in the wake of this incredibly difficult health update that reports have now emerged suggesting Jesy and Zion have ended their romantic relationship. The split remains alleged, as neither party has officially confirmed it publicly.

Focusing on Co-Parenting and Their Daughters' Well-being

A source close to the couple has indicated to tabloids that the split is amicable, with both parents fully united in their focus. "Jesy and Zion remain friends and are fully focused on their daughters," the source claimed. "They are fully united in co-parenting. Their priority continues to be the well-being of their daughters."

Fans first grew suspicious when Jesy appeared on ITV's This Morning without her engagement ring. Furthermore, both Jesy and Zion's Instagram accounts no longer prominently feature photos of their relationship, though past posts likely remain.

This pattern of quietly handling relationship changes is not new for the pair. During their 2024 split, Zion commented on a video about their breakup, writing: "beautiful woman inside and out, wish her nothing but the best."

For now, the public awaits any direct statement from Jesy Nelson or Zion Foster regarding their relationship status. All attention remains on the health of their twin babies, Ocean and Story.
