Former Little Mix star Jesy Nelson has shared the most painful chapter of her life so far — revealing that her eight-month-old twin daughters have been diagnosed with a rare and devastating muscle disease that could alter their futures forever.
In a deeply emotional Instagram video shared over the weekend, the 34-year-old singer fought back tears as she told fans that her twins, Ocean Jade and Story Monroe, have been diagnosed with Spinal Muscular Atrophy (SMA) Type 1 — the most severe form of the genetic neuromuscular condition.
Struggling to keep her composure, Jesy revealed the blunt reality doctors laid before her.
“We were told that they’re probably never going to be able to walk,” she said quietly.
“They may never regain their neck strength, so they will be disabled.”
She added, her voice shaking:
“The only thing we can do right now is get them treatment — and hope for the best.”
A Diagnosis No Parent Is Ever Prepared For
Medical experts explain that SMA Type 1 is a rare genetic disorder that causes progressive muscle weakness, gradually affecting movement, breathing and feeding. There is no cure — but early treatment can help slow the progression and improve quality of life.
Jesy described the weeks following the diagnosis as a living nightmare.
“It’s the most severe muscular disease a baby can get,” she said.
“In just two weeks after finding out, I’ve had to put my babies on breathing machines and do things no mother should ever have to do.”
The singer admitted she never imagined facing such life-altering decisions with children so young.
The First Warning Signs
Jesy revealed it was her own mother who first sensed something wasn’t right.
“A few months ago, my mum noticed the girls weren’t moving their legs as much as they should,” she explained.
Initially, doctors reassured the family that everything was fine. The twins — whom Jesy shares with fiancé Zion Foster — were born prematurely following a high-risk pregnancy but were first declared healthy.
“We were told they looked great,” Jesy recalled.
“But then they started struggling to feed. Slowly… it just got worse.”
That gradual change ultimately led to the devastating diagnosis.
A Plea to Parents Everywhere
In her video, Jesy issued an urgent warning to parents across the world.
“If anyone watching notices these signs in their child, please take them to the doctor or hospital immediately,” she pleaded.
“Time is everything.”
She explained that without treatment, babies with untreated SMA Type 1 may not live beyond the age of two.
“The quicker you act,” she stressed, “the better your child’s life can be.”
A Life Far From the Spotlight
Jesy famously stepped away from Little Mix in 2020 to protect her mental health, later retreating further from public life after intense backlash surrounding her debut solo project in 2021.
After years away from the spotlight, she welcomed her twin daughters on May 15, 2025 — believing she was finally entering a chapter of peace and happiness.
Instead, she now finds herself living between hospital rooms, machines and medical decisions — fighting a very different battle as a mother.
“We’re Just Taking It One Day at a Time”
Despite the heartbreak, Jesy remains resolute.
“We’re doing everything we can,” she said.
“And we’re just hoping.”
As messages of support pour in from fans around the globe, Jesy’s raw honesty has struck a chord — not as a celebrity revelation, but as a mother confronting the unimaginable.
For now, Jesy and her family are focused on treatment, time and hope — holding tightly to every moment with Ocean and Story, and believing that even in the darkest diagnosis, love still leads the way.
