Brave Jesy Nelson says she has been "overwhelmed" by messages of support after revealing her twin girls had been diganosed with a rare genetic condition.
The former Little Mix singer told how seven-month-old Ocean Jade and Story Monroe Nelson-Foster were suffering with Spinal Muscular Atrophy (SMA).
Essex-born Jesy, 34, is now campaigning to get the condition added to the newborn blood spot screening test after an emotional admission her newborns are unlikely ever to be able to walk.
Speaking to Ben Shephard and Cat Deeley during an emotional appearance on ITV's This Morning she said: "I almost feel like I've got a duty of care to raise awareness about it.
"It feels selfish to keep this to myself and not potentially save a child's life. Something that can be done and that is why I'm going to shout to the rooftops about this."
The optional NHS blood test is normally carried out on newborns at five days old and looks for conditions including Sickle Cell Disease, Cystic Fibrosis, and Severe Combined Immunodeficiency.
Jesy found stardom on The X Factor as part of the first group - and only girl group to win the original UK series.
Her twins' diagnosis of the most severe muscular disease" came after months of punishing rounds of tests and appointments.
She said they had not been showing as much movement in their legs as they should be and were struggling to feed properly.
In an emotional video message to her 10 million fans she said: "Essentially, what it [SMA] does is, over time, it kills the muscles to the body, and if it's not treated in time, your baby's life expectancy will not make it past the age of two. It does affect every muscle in the body, down to legs, arms, breathing, and swallowing."
Jesy added: "I am so determined to make this happen, so I'm going to fight as much as I can to make this part of the newborn screening.
"Thank you from the bottom of my heart for the outpouring of support and beautiful messages for me and just so many other families that are dealing with this horrible diagnosis."
