Jesy Nelson confirms split from fiancé Zion Foster following daughters’ rare diagnosis

Former Little Mix singer Jesy Nelson has announced that she and her fiancé, Zion Foster, have split after four years together. The 34-year-old singer made the revelation in a new interview, where she opened up about how the "traumatic experience" of their twin daughters’ health issues had ultimately affected their relationship.

Jesy Nelson says that twin daughters’ rare disorder was a reason in split from fiancé Zion Foster

Jesy and Zion, 26, were first romantically spotted in early 2022. They welcomed their twins, Ocean Jade and Story Monroe, in May of last year and announced their engagement just four months later in September 2025. However, the couple’s life was turned upside down last month when Jesy broke the heartbreaking news that their eight-month-old twins had been diagnosed with spinal muscular atrophy (SMA).

A focus on family

Jesy opened up about the split, revealing that the stress of dealing with such a rare and life-changing diagnosis had made it impossible for her and Zion to keep their romantic relationship alive. "We have been through such a traumatic experience and for us, our girls are our main priority," she said.

She said that although she and Zion are still friends, the "energy wasn’t right" between them. Jesy also said that they are now completely dedicated to being the best parents possible and giving their children a "positive, happy, and uplifting" environment.

Dealing with the future

SMA is a very rare genetic neuromuscular disease that results in muscle wasting and paralysis. In a tearful video posted on Instagram in January, Jesy told her fans that the girls would probably be disabled and may never be able to walk again or regain strength in their necks.

Looking back on the diagnosis, Jesy said that she is feeling "sadness" and "anger" that the disease was not diagnosed earlier but that the twins are doing well at the moment. For now, Jesy is just trying to live in the moment and not get overwhelmed by the uncertainty of what the future may hold. "f I try to look too far into the future, I will drive myself crazy," she confessed.
