Lady Gaga was forced to postpone upcoming shows in Chicago, Detroit, and Hamilton, Ontario, after suffering from "severe joint inflammation," Reuters reports.
"I am completely devastated and heartsick," she said in a statement provided by Reuters. "I've been hiding this injury and pain from my staff for a month, praying it would heal, but after last night's performance, I could not walk."

The singer said she had been diagnosed with synovitis, an inflammation of the joints that can result from a sprain or strain.
"To the fans in Chicago Detroit & Hamilton I hope you can forgive me, as it is nearly impossible for me to forgive myself. I'm devastated & sad," she tweeted Tuesday to her 34 million followers, adding, "It will hopefully heal as soon as possible, I hate this. I hate this so much. I love you and I'm sorry."
The three postponed concerts were part of Lady Gaga's Born This Way Ball, the singer's third world tour. The tour includes 110 dates on every continent except Antarctica, Billboard reports, and promotes Lady Gaga's second studio album, "Born This Way." The singer has already played dozens of shows in Australia, Asia, and Latin America, says Billboard, and these four postponed concerts were part of her North American leg, which is expected to continue into March, according to her website.
Lady Gaga's previous 'Monster Ball' tour grossed $188 million from 167 shows, according to Billboard, and was nearly "the highest-grossing tour ever by an artist making their global run through arenas and stadiums."
