Perhaps she needs to rethink her fitness sessions with personal trainer Tracy Anderson, which involve gruelling two-hour workouts six days a week while drinking coconut water to keep energy levels high.

Miss Anderson is based in New York but flew to London to help the star prepare for her European tour.

She was introduced to Madonna by Gwyneth Paltrow, who began working out after giving birth to son Moses in 2006.

Earlier this month, Miss Anderson said: 'I have completely changed Madonna's body. I told her to forget everything she had been taught before and to give up yoga, which can make you look terribly veiny.

'Madonna's very healthy and looks fantastic but those veins have nothing to do with me.'
