Jesy Nelson and Zion Foster Split After 3 Years Amid Twins' SMA Diagnosis
Jesy Nelson and Zion Foster split after three years

In a heartbreaking turn of events, former Little Mix singer Jesy Nelson and her musician fiancé Zion Foster have reportedly called off their engagement and ended their relationship. The news comes as the couple navigate the devastating recent diagnosis of their twin daughters, Ocean Jade and Story Monroe, with spinal muscular atrophy (SMA).

A Rollercoaster Romance: From Friends to Family

Jesy Nelson, 34, and Zion Foster, 26, first got together in late 2022, after a long-standing friendship. Their romance began shortly after Jesy's split from her previous partner, producer and rapper Harry James, known as Fugutive. The couple's relationship was marked by an on-again, off-again pattern from the start, with their first brief separation occurring shortly after they began dating.

At the time, a source close to the pair cited conflicting schedules and their eight-year age gap as contributing factors. "Jesy is in a different head space from Zion these days," an insider told The Mirror in 2022. "She is after all a few years older than Zion and has a different way of looking at things. They had a great trip abroad but since they got back, Jesy has realized it's time to move on."

Public Breakups and a Surprise Pregnancy

Their turbulent relationship continued, with another apparent split in August 2023 and a reconciliation in 2024. Tensions flared again in September 2024, when both parties wiped all traces of each other from their social media profiles. A video on OK!'s TikTok channel fuelled speculation, prompting Zion himself to confirm the breakup in the comments, writing: "Beautiful woman inside and out. I wish her nothing but the best."

A source told The Sun at the time, "Jesy and Zion split last month and have completely cut ties with each other. It’s not the first time they have broken up but friends think it’s for good this time."

In a stunning reversal, Jesy announced she was expecting twins in January 2025, leaving fans shocked. She shared the news on social media with a photo of her baby bump, captioned: "She’s eating for 3 now," followed by two baby emojis. The couple welcomed their daughters and seemed stronger than ever, announcing their engagement just four months later in September 2025. Jesy lovingly referred to Zion as her "best friend" in the engagement post.

Devastating Diagnosis and Mounting Pressure

The couple's joy was recently overshadowed by the news that their infant twins have been diagnosed with spinal muscular atrophy, a rare genetic condition that affects motor neurons. Jesy has since been using her platform to raise awareness for SMA.

Friends and sources now suggest that the immense emotional strain of coping with their children's diagnosis, combined with the existing pressures of their high-profile lives, may have contributed to the final breakdown of their relationship. The split marks the end of a three-year journey that saw the pair transition from friends, to lovers, to parents, and finally to ex-partners.

The couple have not yet made an official public statement regarding their separation.
