The singer claims the Tesco worker, 50, complained to him about being unable to keep up with the other contestants.

Mary has show signs of cracking under the pressure,’ says John, 30.

‘She’s got arthritis in both knees and is struggling with the long hours. 

‘I tried to keep her strong, but now I’m gone, she needs to try to keep it together.’

John – who was mentored by Louis Walsh, 58 – was voted off The X Factor in week 3.
