Madonna collapses twice onstage

The 51-year-old singer, notorious for her punishing fitness regime, had left her troupe worried after she passed out midway a gig on Saturday while singing ‘Holiday’. She refused to take a break from her punishing schedule despite her exhaustion. “Madge was really worried backstage. She had to sit down for a longer break than usual between songs. She refused to end the show or take a break after the Holiday dizzy spell. It turns out she’s suffering from exhaustion,” a source said.
