Through a series of Twitter messages, Mother Monster revealed that she's been hiding the "show injury and chronic pain" from her staff "for sometime now," but now her condition has worsened.

"I didn't want to disappoint my amazing fans," Gaga tweeted. "However after last night's performance I could not walk and still can't. It will hopefully heal as soon as possible, I hate this. I hate this so much. I love you and I'm sorry."

According to The Associated Press, the dates in question include Feb. 13-14 in Chicago, Feb. 16 in Detroit and Feb. 17 in Hamilton, Ontario, Canada.

Makeup dates for these cancellations will be announced later, according to the news source.
