Jesy, who has been open about her challenges as a single parent, expressed the immense worry every parent feels when their little ones are suffering in the heat.

The heatwave has brought record temperatures, making it particularly tough for families with young children. Jesy’s honest admission has resonated with many parents going through similar difficulties.

Despite the sadness, Jesy remains focused on doing everything she can to keep her twins safe and comfortable during the blistering conditions.

Her vulnerability in sharing this personal moment has drawn an outpouring of love from fans and fellow celebrities alike.

Sending strength to Jesy and her beautiful family during this tough time.

Weeks after sharing that her baby girls, Ocean Jade and Story Monroe, were diagnosed with spinal muscular atrophy (SMA) Type 1, she said she believes her girls will “defy all the odds” and live past the age of 2.

During the Wednesday, Feb. 4, episode of Jamie Laing’s Great Company podcast, the 34-year-old Little Mix singer explained more about her daughters’ condition.

“So spinal muscular atrophy is a muscular wasting disease, and what it does is, well, they don’t have a gene that we all have in our body. So because of that, their muscles are deteriorating and wasting away,” she said.

Nelson and her former fiancé, musician Zion Foster, welcomed their twins prematurely on May 15, 2025, weeks after the new mom underwent emergency surgery. She shared news of their diagnosis last month.

“And if you don’t get them treatment in time, eventually the muscles will all just die, which then affects the breathing, the swallowing, everything, and they will die before the age of 2,” she continued on the podcast on Wednesday.

After Laning expressed sympathy, the mother of two replied, “I just have to accept it, and now I just try and make the best out of this situation.”

“I really believe that they are going to defy all the odds. I really believe that because they already have. It’s mad. They were in my belly. They had TTTS [Twin-to-Twin Transfusion Syndrome],” Nelson said.

The rare and serious syndrome affects multiples who “share one placenta (afterbirth) and a network of blood vessels that supply oxygen and nutrients essential for development in the womb,” per John Hopkins Medicine.

The condition creates an imbalance of nutrients prior to their birth.

“I see everything through a completely different lens ‘cause I’m like, they had that, but they also had SMA, and then they just went on to fight it all,” Nelson said of her twins.

During their conversation, the English pop star mentioned that she found out about the spinal muscular atrophy (SMA) Type 1 diagnosis while her twins were in the hospital’s neonatal unit after they were born prematurely at 31 weeks due to the TTTS.

In an emotional video shared to her Instagram account on Jan. 4, “after the most grueling three, four months, and endless appointments,” Nelson disclosed her daughters’ muscular disorder.

“We were told that they’re probably never gonna be able to walk, they probably will never regain their neck strength so they will be disabled. And so the best thing we can do right now is to get them treatment and then just hope for the best,” she said.

Nelson called the past three months “the most heartbreaking time of my life,” adding that she felt like she was “grieving the life I thought I was going to have with my children.”

Before ending, Nelson said she was grateful her babies were still with her and urged other parents to bring their children to the doctor at the first sight of any symptoms because “time of the essence” when it comes to saving a life.
