Madonna is taking time to heal after a health scare, which will postpone at least some of her Celebration world tour that had been set to commence next month.

In a post shared to his verified Instagram, Guy Oseary, Madonna's longtime manager, shared that the 64-year-old icon "developed a serious bacterial infection which led to a several day stay in the ICU" on Saturday.

"Her health is improving, however she is still under medical care. A full recovery is expected," Oseary continued.

"At this time we need to pause all commitments, which includes the tour," he added. "We will share more details with you as soon as we have them, including a new start date for the tour in for rescheduled shows."

Madonna's next tour, titled the Celebration tour, was scheduled to kick off July 15 in Vancouver, Canada, followed by two dates in Seattle starting on July 18. The tour was set to continue throughout the United States and Canada through early October, before heading to Europe.

Madonna also added supplemental dates in the US in December and January, followed by four show dates in Mexico City.
