The Emotional Split of Little Mix Star Jesy Nelson

EXCLUSIVE Showbiz Celebrity JESY LOVE SPLIT Little Mix star Jesy Nelson has announced her split from fiancé Zion Foster, bringing to an end a relationship that lasted four years. The news comes as the singer is working tirelessly to raise awareness for Spinal Muscular Atrophy (SMA) and campaigning for it to be included in newborn screenings.

The Shocking Diagnosis

On January 18, 2026, sources revealed that Nelson and Foster had split up. The news is particularly poignant as the couple’s twin daughters, Ocean Jade and Story Monroe, were recently diagnosed with Spinal Muscular Atrophy Type 1 (SMA), one of the most severe forms of this rare disease affecting muscle strength and movement.

According to a source close to the pair: “She and Zion remain friends and are fully focused on their daughters.” The twins’ condition has undoubtedly put immense pressure on their relationship, with both parents now co-parenting in unity for the sake of their children’s future well-being. Ocean Jade and Story Monroe have already undergone intensive treatment at Great Ormond Street Hospital in London.

Working to Make a Difference

Jesy Nelson has been working tirelessly to raise awareness about SMA, advocating for it to be included in the NHS newborn heel-prick test, which currently screens for ten other conditions. In January 2026, she appeared on ITV’s This Morning and shared her journey with fans, emphasizing that despite the challenges, there is hope.

“I just need you to know that I am so determined to make this happen,” said Jesy Nelson. “So I am going to fight as much as I can to make this part of the newborn screening.”

A Life-Changing Diagnosis

Both Ocean Jade and Story Monroe were diagnosed with SMA Type 1, which affects muscle strength and movement in severe ways. The diagnosis came after Janice Nelson first noticed limited leg movements in her granddaughters. Untreated, the life expectancy for babies with this condition is only two years; however, early intervention can significantly improve quality of life.

Despite the challenges ahead, Jesy remains optimistic: “I truly believe that my girls will defy all odds,” she said. “And with the right help, they will fight this and go on to do things that have never been done.” The singer has launched a petition calling for a non-invasive £4 blood test at birth to screen for SMA, aiming to prevent 33 babies from needing wheelchairs each year.

A Long Journey in the Spotlight

Jesy Nelson’s journey into motherhood and her ongoing battle with SMA has been far from easy. She first rose to fame as a solo artist before joining Little Mix, where she became one of the most recognizable faces in pop music. The band’s success was marked by numerous chart-topping hits and international recognition.

However, in 2020, Jesy announced her departure from the group due to mental health concerns. She has since focused on raising awareness for SMA and sharing her experiences with fans through various media platforms.

Supporting Each Other Through Adversity

While the split between Jesy Nelson and Zion Foster is a bittersweet moment, their commitment to co-parenting shows that love can transcend personal relationships. As they navigate the challenges of raising SMA-affected children together, their shared goal remains clear: ensuring that future generations have access to early detection and treatment.

The couple’s determination to advocate for change highlights the importance of community support in facing life’s greatest battles. With their combined efforts, there is hope that Ocean Jade and Story Monroe will not only thrive but also inspire others with their resilience.
