At first, she only canceled a couple of dates, but now she is pulling the plug on the whole thing.....Lady Gaga has been forced to cancel her entire tour due to illness. Gaga tweeted, "There's an unfortunate announcement coming out right now, concerning myself and the Born This Way Ball. I'm so sorry. I barely know what to say. I've been hiding a show injury and chronic pain for sometime now, over the past month it has worsened. I've been praying it would heal. I hid it from my staff, I didn't want to disappoint my amazing fans. However after last night's performance I could not walk and still can't. I hope you can forgive me, as it is nearly impossible for me to forgive myself. Gaga reportedly has a case of synovitis, which is a severe inflammation of joints. Gaga will need to get surgery on her hip to repair the labral tear she has on the right side. After the surgery she will reportedly require extensive down time. Fans can get refunds for all performances, according to Live Nation.
