Russell Watson has opened up to his I'm A Celebrity... Get Me Out Of Here! campmates about his past battles with brain tumours.
The opera singer had an operation to remove a benign tumour in 2006 but just a year later he was forced to undergo emergency surgery for a second growth, leaving him critical in intensive care.
"I was in the MRI scanner and I could see this long strip of light, like when you're a kid and you used to keep your bedroom door open," he said.
"It was a light strip and I was thinking if I go to that door I'm out of here and the pain stops and I'm away. All I could think about was my children and slowly slowly whilst thinking about my children the clatter clatter of the MRI came back and I thought 'I'm going to beat this'."
Following the removal of the tumour, Watson has been forced to take a daily cocktail of drugs to keep his hormones in check.
