Looks like touring around the world has really taken it out of Lady Gaga, who took Facebook and Twitter yesterday to tell al her little monsters how she has been battling chronic pain from a severe injury while on tour, and has postponed a number of her upcoming concerts because she can barely walk after hurting herself more than a month ago.

Suffering from something called synovitis (which Wikipedia tells us is severe inflammation of the joints), Mother Monster revealed she was forced to cancel a number of her shows on her Facebook page saying, in typical Gaga hyperbole: 'I barely know what to say. I've been hiding a show injury and chronic pain for some time 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.' And with that she postponed two concerts in Chicago, one in Detroit and one in Hamilton, Ontario. Maybe that explains the weight gain and all the weed smoking she was up to recently.

The martyrdom continued with : 'I hope you can forgive me, as it is nearly impossible for me to forgive myself. I'm devastated & sad. It will hopefully heal as soon as possible. I hate this. I hate this so much. I love you and I'm sorry.'

This has nothing to do with your legal troubles does it now Gaga? And any guesses on what happened? She's no stranger to injury, having been whacked on the head with frightening frequency, and falls off her piano quite a lot, but this sounds slightly more serious.
