Little Mix singer Jesy Nelson has reportedly split from her longtime love, fiancé Zion Foster, just weeks after revealing that her 8-month-old twins are battling a severe form of muscle disease.
Nelson, 34, and Foster have gone their separate ways after four years together, but remain friends and coparents, The Sun reported on Monday, January 19.
The couple got engaged in September 2025, just four months after Nelson welcomed their twin daughters, Story and Ocean.
Us Weekly has reached out to Nelson’s representatives for comment.
Earlier in January, Nelson revealed the heartbreaking news that her daughters had been diagnosed with spinal muscular atrophy (SMA) type 1, a genetic condition that causes muscles to weaken.
“A few months ago, my mum noticed that the girls were not showing as much movement in their legs as they should be,” Nelson shared in a January 4 Instagram 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 shared. “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.”
Nelson continued, “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.”
Several celebrities announced in 2025 that their families are expanding. In November, Carly Rae Jepsen and Cole M.G.N. announced baby No. 1, while 90 Day Fiancé stars Emily and Kobe Bieberly shared they are expecting baby No. 4. Later that month, both Lindsay Arnold and Hallmark actress Erin Krakow announced they are expecting new additions […]
“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,” she explained. “If it’s not treated in time, your baby’s life expectancy will not make it past the age of 2.”
Nelson said that Story and Ocean quickly underwent treatment for SMA type 1, which the little ones have now completed.
“When [the doctors] assessed the girls, we were told they’re probably never going to be able to walk,” Nelson said through tears. “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,” the musician said. “It has just been endless, endless amounts of hospital appointments. I practically feel like the hospital has become my second home.”
An emotional Nelson added, “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.”
