Jesy Nelson splits from fiancé amid twins' health battle

Former Little Mix star Jesy Nelson and her fiancé, Zion Foster, have reportedly called off their engagement and separated. The couple's decision comes during an immensely challenging period following a devastating health diagnosis for their twin daughters.

A Family's Focus Amid Heartbreak

The pair, who welcomed their twin girls Ocean Jade and Story Monroe in recent years, have faced a "tough few years," according to sources. This difficulty was compounded when their daughters received a diagnosis of Spinal Muscular Atrophy Type 1, a serious genetic condition that affects muscle strength and movement.

Despite the personal split, a source close to the couple has emphasised that their primary concern remains unwavering. "She and Zion remain friends and are fully focused on their daughters," the insider revealed. "They are fully united in co-parenting. Their priority continues to be the well-being of their daughters."

United Front for Co-Parenting

The separation, reported on 18 January 2026, appears to be amicable, with both parties committed to putting their children first. The source's comments highlight a determined effort to maintain a stable and supportive environment for Ocean and Story during their health journey.

Spinal Muscular Atrophy (SMA) Type 1 is the most severe form of the condition, typically diagnosed in infancy. The news of their daughters' diagnosis has undoubtedly shaped the couple's recent experiences and informed their current priorities.

Navigating a New Chapter

While their romantic relationship has ended, Jesy Nelson and Zion Foster are adamant about their future roles as parents. The model and the former X Factor winner have chosen to channel their energy into a collaborative parenting partnership, ensuring their twins receive consistent care and love from both of them.

This approach to separation, focusing on friendship and shared responsibility, is often seen as a way to minimise disruption for children, especially those facing significant health challenges. The couple's reported stance suggests a mature and child-centred resolution to their personal changes.

Fans of the singer have followed her journey through motherhood since she announced her pregnancy, and this new development marks a poignant and private chapter for the family as they navigate complex personal and medical circumstances together, albeit in a reconfigured relationship.
