The Take That boys have been eating what they want since Christmas and have decided to liven up their pre-tour diets by raising the stakes.
Robbie told The Sun, 'Me and Gary vary in weight. We go up and down by the week.
'Gary and the boys were at my house in LA last week when Gary turns to me and says, 'I won't be needing these clothes soon, do you want them?' – 'cos he's going on a diet.
'That was the day I thought, 'Right, if you're eating a lettuce, I'm eating half a lettuce’.
'There is now a serious game on to see who can get the thinnest for the tour.
'You know The Machinist with Christian Bale? I'm going for Christian Bale.'
The band has called in five personal trainers and a nutritionist called Jasmine who will work with them until their tour in May.
