Lady Gaga Postpones Shows Over 'Chronic Pain'

Lady Gaga is postponing three performances because she's suffering from synovitis, or "severe inflammation of the joints," according to her Twitter account. She's delaying shows in Chicago, Detroit, and Hamilton, Ontario, the BBC reports. "To the fans in Chicago Detroit & Hamilton I hope you can forgive me, as it is nearly impossible for me to forgive myself. Im devasted (sic) & sad," she tweeted, per Access Hollywood.

"I’ve been hiding a show injury and chronic pain for sometime now, over the past month it has worsened ... I hid it from my staff, I didn’t want to disappoint my amazing fans. However after last nights performance I could not walk and still can’t." A performance in Philadelphia Feb. 19 is set to go on as planned, the BBC notes. (More Lady Gaga stories.)
