Madonna's "Celebration" tour has been postponed after suffering a bacterial infection that landed her in the intensive care unit. Page Six reported that the Material Girl was found unresponsive over the weekend and subsequently rushed to a New York City hospital. There, she was reportedly intubated "for at least one night before having the tube removed."The report noted that the pop star is alert, responding and no longer in the ICU.Madonna's daughter, Lourdes Leon, was by her mom's side throughout the medical incident. Amid speculation, Madonna's manager, Guy Oseary, confirmed the hospitalization but shied away from discussing the alleged intubation.
