Madonna has just postponed her career-spanning ‘Celebration’ tour due to what her manager called a “serious bacterial infection.”

Madonna’s manager Guy Oseary wrote on Instagram Wednesday that she had spent several days in an intensive care unit after becoming ill on Saturday.

The tour was set to kick-off in Vancouver on July 15th.

“Her health is improving, however she is still under medical care,” Oseary wrote. Live Nation has also confirmed that the tour will be postponed, but no info has been shared yet. The good news is that she is expected to make a full recovery.
