Jesy Nelson and Fiancé Zion Foster Split, End Engagement

English singer Jesy Nelson and fiancé Zion Foster have called off their engagement and split up. 

Nelson, 34, whose twin girls have a life-threatening condition, is no longer wearing her ring after getting engaged four months ago. 

A source said, “She and Zion remain friends and are fully focused on their daughters.”

The twins — Ocean Jade Nelson-Foster and Story Monroe Nelson-Foster — have Spinal Muscular Atrophy Type 1, the most severe form of a rare disease affecting muscle strength and movement.

The former couple was told it is unlikely the girls will ever walk, and may face serious breathing and swallowing difficulties.

The source added: “They are fully united in co-parenting. Their priority continues to be the well-being of their daughters.”

Nelson and Foster were first linked together in January 2022 after years of friendship. In August 2024, they released a song together titled “Mine.” 

In January 2025, they announced they were expecting identical twins. The pregnancy was later classed as high-risk after the girls were diagnosed with twin-to-twin transfusion syndrome (TTTS), a rare condition affecting identical twins who share a placenta.

Nelson had in-utero surgery and spent several months under medical supervision before the twins were born prematurely in May.

The former Little Mix member’s mum, Janice, first raised concern when she noticed they were showing limited leg movements.

Symptoms of SMA depend on the type of condition, but the most common include floppy or weak arms and legs, as well as swallowing and breathing problems.

If untreated, the life expectancy of a baby with SMA Type 1 is two years. Early intervention is ­considered critical in limiting long-term impacts. If the twins had been tested and treated in time, there is a chance they would have avoided disability.

It is now unlikely they will regain their neck strength after the disease caused nerve cells to die, leading to progressive muscle weakness.

The twins are under the care of Great Ormond Street Hospital in ­central London and have received treatment, including a one-off gene-therapy infusion approved by the NHS.

Nelson is working tirelessly to raise awareness of SMA and campaigning for the condition to be added to the NHS newborn heel-prick test, which currently screens for ten other conditions.

She appeared solo on ITV’s "This Morning days" after posting an emotional video on social media about her twins’ health battle.

Nelson 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 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.”

The singer added, “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.”

The Brit Award-winner has launched a petition to force the Government to enforce a non- invasive £4 blood test at birth. It could help avoid 33 babies a year left needing a wheelchair for life.

Nelson told fans, “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. I’m genuinely overwhelmed by the amount of support,".

“I just want to say thank you to everyone that shared it, to everyone that wants to learn about it, that’s taking the time to watch it and send me beautiful messages, " she added. "They’ll probably never regain their neck strength, they are going to be in wheelchairs. But there have been so many stories where parents have been told this, and their children have gone on to do incredible things."

Despite no longer being in a relationship, Foster continues to support Nelson as they raise their daughters together. He has written a touching poem to his “two little warrior girls who already know how to fight”.
