Madonna had pushed herself so hard to get ready for her 84-date world tour that she had relied upon painkillers to survive, sources said.

“She was working overtime, but she clearly burnt herself out and people around her have been politely reminding her that she is not 45 anymore, let alone 25,” a source previously said, comparing her to younger stars like Taylor Swift and Pink.

“She needed to pace herself. Pushing herself so hard was extremely risky.”
