Jesy Nelson could be seen in tears over the weekend as she explained she will need an emergency procedure to help her unborn twins.
The former Little Mix singer, 34, and her partner Zion Foster, announced they were expecting twins earlier this year.
But last week, Jesy shared a heartbreaking update with fans, explaining she has been suffering some complications in her pregnancy.

"So we are having identical twins, which is so exciting, we actually can't believe it. But unfortunately, there are complications that come with having identical twins," Jesy said on Instagram.
"The type of twins we are having are called Mono/Di twins, and with that, so normally, most twins will have two placentas that they feed off of.
"But when you have Mono/Di twins, that means your twins live off one placenta, which can lead to lots of complications.
"One of them being one baby might take all the nutrients, the other might, which is really awful to say, but could lead to both babies dying and at the moment, I am currently pre stage TTTS, which is twin to twin transfusion, and I'm being monitored very closely."
Over the weekend, Jesy updated her followers, explaining that she will need an emergency procedure after suffering from some of the symptoms she was told to watch out for.
"I've been feeling a bit poorly the last few days, been having a few of the symptoms I need to watch out for which is like my belly tightening, struggling breathing, so today we came into the hospital to just have a check up basically," she said.
"Unfortunately, the symptoms have got worse so they now have to perform the procedure, which is obviously not what we wanted to happen but it's necessary because it's going to give our babies the best chance of surviving.
"So we're just waiting to go in and we're just hoping and praying for the best really.
"I feel absolutely gutted because I was really hoping we wouldn't be in this position."
What is Twin-to-Twin Transfusion Syndrome?
TTTS, or Twin-to-Twin Transfusion Syndrome, is a rare pregnancy condition that can affect identical twins or multiples, according to Hopkins Medicine.
This occurs when twins share one placenta and a network of blood vessels that provide oxygen and nutrients that help with development in the womb.
Occasionally, the vessel connections within the placenta are not evenly dispensed, causing an imbalance in blood exchange between the twins.
One of the twins becomes the donor twin, giving away more blood than it receives, and can be at risk of malnourishment and organ failure, whereas the recipient twin receives too much blood and can overwork their heart.
The star announced she was pregnant back in January, taking to Instagram to share the happy news alongside a polaroid picture showing off her growing baby bump.
"She’s eating for 3 now," Jesy wrote.
After dating over the last couple of years, Foster and Nelson were first linked together back in 2022, before reportedly splitting for the first time in November 2023.
However, after reuniting, they appeared to part ways in September last year. At the time, the musician commented on a social media post: "Beautiful woman inside and out, wish her nothing but the best."
