The 37-year-old star recently had to cancel a tour date with band Take That after eating a lobster that gave him food poisoning.
However he is now concerned about what to eat and has reportedly asked for a plate of fresh melon and four apples to be put in his room before shows.
A source said to UK newspaper Daily Star: 'It hasn't been pretty. It's all down to that dodgy lobster. Jason [Orange] and Mark [Owen] wanted to go ahead and do it without him, so as not to let down the fans.
'But there was something to do with the insurance that stopped them.'
