Amanda Holden encouraged her Heart Breakfast radio show listeners to support the NHS as she recounted how they had once saved her life, as well as provided her with care when her son was stillborn.
It came as she discussed the 'Clap for Carers' initiative which is set to take place on Thursday as UK residents have been urged to clap from outside their homes to demonstrate their support for the NHS amid the coronavirus outbreak.
The Britain's Got Talent judge declared: "[The NHS] have always been important to Great Britain. They've always been important to all of us, but now more than ever we should be appreciating them.
"I know for me personally, without getting tearful, they saved my life, literally. My sister was in a car accident two years ago, they saved her life, literally. They looked after us as a family when we lost a baby."
Holden, 49, sadly lost her son Theo in 2011 when he was seven months old as his heart at stopped beating. It came a year after she had suffered a miscarriage at 16 weeks.
She has previously discussed how she was left in a critical condition following on from the birth of her second daughter, Hollie, now eight.
