R&B singer Alexandra Burke says her mother, who is battling severe kidney failure, has refused to take one of her kidneys.
Soul II Soul star Melissa Bell, 48, is battling kidney failure and spends eight hours a day on dialysis, reported The Mirror.
She is on the transplant list but has a rare blood type. She could die without a new organ but says it would be "wicked and selfish" to accept her daughter's kidney.
"I've tried three or four times. But mum made the choice because the doctors said it could mean I wouldn't be able to conceive. She didn't want to �restrict me. But I was �willing to adopt anyway," Burke said.
Bell's ill health came to light when Burke was competing on 'The X Factor' in 2008.
