Former Little Mix star Jesy Nelson and her fiancé Zion Foster have reportedly broken up after four years together.
Sources close to the pair say the split was mutual, and their main focus is successfully co-parenting their twin daughters, Ocean Jade and Story Monroe.
The reported break-up comes just months after the pair got engaged, and follows a stressful year for the pair.
Jesy and Zion welcomed their little girls prematurely at 31 weeks in May 2025 and were later told their twins had been diagnosed with a life-threatening condition, Spinal Muscular Atrophy Type 1 (SMA Type 1).
According to the NHS, this is the most severe form of the rare genetic condition, which affects muscle strength and movement, and can cause serious breathing and swallowing difficulties. Without treatment, babies often have a life expectancy of around two years.
It was later revealed that Ocean and Story’s diagnosis came after irreversible nerve damage had already occurred.
Speaking to The Sun, a source close to the pair said: “She and Zion remain friends and are fully focused on their daughters.” Another added, “They are fully united in co-parenting. Their priority continues to be the well-being of their daughters.”
Jesy, 34, and Zion, 26, first began dating in 2022 after years of friendship, and in January 2025, they announced they were expecting identical twins. This news quickly turned complicated when Jesy’s pregnancy was later classed as high-risk as the twins were diagnosed in utero with twin-to-twin transfusion syndrome (TTTS).
This rare condition affects identical twins who share a placenta and saw Jesy undergoing surgery while pregnant and spending months under medical supervision before Ocean and Story were born.
Soon after their birth, further concerns were raised. Jesy’s mum, Janice, was reportedly the first to notice the girls were showing limited leg movement and the twins were later diagnosed with SMA Type 1.
Doctors have reportedly told Jesy and Zion that the girls are unlikely to ever walk and may not regain neck strength, meaning they will likely require wheelchairs. The babies are currently under the care of Great Ormond Street Hospital in London and have received treatment, including a one-off gene therapy infusion approved by the NHS.
Despite the heartbreak, Jesy has been speaking out to raise awareness. Appearing on ITV’s This Morning, she said: “We’ve been told they will probably never walk. They’ll probably never regain their neck strength. They are going to be in wheelchairs.”
But she added: “There have been so many stories where parents have been told this, and their children have gone on to do incredible things. So I believe that you’ve just got to manifest this into existence.”
Jesy went on: “I truly believe that my girls will defy all odds. And with the right help, they will fight this and go on to do things that have never been done.”
Since the diagnosis, Jesy has committed herself into campaigning for change. She has launched a petition calling for SMA to be added to the NHS newborn heel-prick screening test. This simple £4 blood test could help prevent long-term disability if the condition is caught early.
She told supporters, “I just need you to know that I am so determined to make this happen. So I am going to fight as much as I can to make this part of the newborn screening.”
Four Nine has reached out to Jesy’s reps for comment.
