The singer was scheduled to perform three shows in Boston starting Friday night as part of her worldwide Madame X tour.

Madonna announced on Wednesday that she'd made the difficult decision to cancel all three of her shows in Boston scheduled for Friday, Saturday and Sunday.

Taking to Instagram, the pop star wrote that she's following doctor's orders in making this decision, even though it's incredibly difficult for her.

"Please forgive this unexpected turn of events," she wrote. "Doing my show every night brings me so much joy and to cancel is a kind of punishment for me, but the pain I’m in right now is overwhelming, and I must rest and follow doctor’s orders so I can come back stronger and better and continue the Madame X journey with all of you."

Madonna is currently touring in support of "Madame X," her fourteenth studio album released over this past summer and becoming her ninth effort to debut atop Billboard's Top 200 chart.

The worldwide theater tour kicked off September 17 in New York City and is set to conclude after 87 shows on March 8, 2020 in Paris. At this time, though, it is unclear if Madonna will be forced to cancel any other future dates.

Unfortunately, in confirming this news, her tour promoter revealed that the Boston shows will not be made up "due to the tight scheduling through the balance of the year." Instead, "refunds will be automatically issued to the credit card on which they were ordered."

This weekend's shows aren't the first cancellations for Madge on this tour, either. She previously had to cancel two shows in Brooklyn and one in Los Angeles for production issues and injury.

After this weekend's aborted shows, the Madame X Tour heads to Philadelphia for four shows at the Metropolitan Opera House starting December 7. Hopefully, that additional time will allow whatever is ailing her to heal up so the show can go on.

While she didn't go into specifics as to what specifically is causing her so much pain right now, Variety notes that the singer told an audience earlier in the month that she was suffering from a torn ligament and having issues with her knees. That said, this may be a totally unrelated ailment.
