Alexandra Burke’s mother and Soul II Soul singer Melissa Bell is currently fighting a severe kidney failure which requires her to be connected to a dialysis for eight hours a day.

And despite her offers, the 48-year-old who has a rare blood type refuses to take daughter Alexandra’s kidney saying that to take the donor would be “wicked and selfish”.

Alexandra Burke told the Mirror:

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.

Melissa is currently on the donor transplant list and her illness came to light when she struggled to attend Alexandra’s performances on the X Factor in 2008.
