X is not marking the spot for Madonna's Madame X Tour.
On Sunday, the 61-year-old superstar took to social media to announce that she was cancelling that evening's Paris performance of the problem-plagued production, citing an alleged injury she sustained during a concert a few nights prior.
"Here I Am _ Flesh and Blood. If only knees didn't twist and cartilage didn't tear and nothing hurt and tears never fell out of our eyes," she wrote in a lengthy Instagram post. "But alas they do."
The "Like A Virgin" singer has had a mounting list of injuries since the all-theater tour kicked off in New York City last fall.
Sunday's cancellation marks the 13th time she pulled out of the 78-date Live Nation-produced trek due to injury.
With the production issues at two separate stops in New York City and Los Angeles factored in, Madame X has suffered 15 show cancellations in total.
Madonna went into further detail of how she got hurt this time.
"I Fell 2 nights ago on stage when a chair was literally pulled out from underneath me by mistake and I landed on the floor on my tail bone," she revealed. "I made it thru the show last night but just barely because I hate disappointing. However today even I can see that this broken doll held together with tape and glue, needs to stay in bed and rest for a few days so she can finish the tour with a smile on her face and in one piece."
She concluded her note: "Thank You for your understanding Paris!"
The remainder of the Madame X Tour was set to play Paris' Le Grand Rex, scheduled for March 3 through March 11.
Though the seven-time Grammy winner noted in her post that she needs to rest "for a few days," there has been no word yet on how the dates will be impacted.
