Little Mix alum Jesy Nelson has reportedly split from fiancé Zion Foster just two weeks after sharing their 8-month-old twin daughters were diagnosed with a severe form of muscle disease.
According to a report in The Sun published on Monday, Jan. 19, the pair have broken up after four years together, but remain friends and committed to co-parenting.
The couple recently got engaged in September 2025, just four months after their daughters Story Monroe and Ocean Jade were born on May 15.
Neither Nelson nor Foster have commented publicly on the alleged breakup.
On Sunday, Jan. 4, Nelson shared that her daughters had been diagnosed with Spinal Muscular Atrophy (SMA) Type 1 via Instagram.
“A few months ago, my mum noticed that the girls were not showing as much movement in their legs as they should be,” Nelson said in the video. “[It] wasn’t really a concern to me at the time because from the minute I left the NICU, I was told, ‘Your babies are premature, so do not compare your babies to other babies. They won’t reach the same milestones. Take them as they are.’”
“When the healthcare visit came, we were told, ‘They look great, they’re healthy and everything is fine,’” the singer continued. “A few signs then started to show a bit later on that they were struggling to feed properly. It was getting gradually less and less and less.”
“Long story short, after the most grueling three [or] four months and endless appointments, the girls have now been diagnosed with a severe muscle disease called SMA type 1,” she added. “Type 1 is the most severe type that a baby can get. It stands for spinal muscular atrophy, which can affect every muscle in the body down to legs, arms, breathing, swallowing and … over time it kills the muscles in the body.”
Nelson noted that her twins quickly began treatment after receiving their diagnosis. If left untreated, life expectancy for babies with SMA type 1 is only 2 years of age.
“When [the doctors] assessed the girls, we were told they’re probably never going to be able to walk,” Nelson said. “They’ll probably never regain any strength, so they will be disabled. The best thing we can do right now is get them treatment and just hope for the best.”
“I’m so grateful because if they don’t have it, they will die,” she continued. “It has just been endless, endless amounts of hospital appointments. I practically feel like the hospital has become my second home.”
Nelson, visibly emotional, concluded, “The last few months have been the most heartbreaking time of my life. I literally feel like my whole life has done a 360. I almost feel like I’m grieving the life I’m not going to have with my children. I [do] have to be grateful because, at the end of the day, they’re still here and that’s the main thing. They’ve had their treatment and I truly believe my girls will defy all the odds and, with the right help, they will fight this and go on to do things that have never been done.”
