Lady Gaga's masses of monsters are probably moping around in their latex dresses because she recently announced that she had to postpone concerts in Chicago, Detroit, and Ontario—but with good reason. Apparently Gaga has been diagnosed with Synovitis and has been hiding this injury throughout her tour. It all finally caught up with her when she couldn't walk after a performance. She apologized to all her fans via Twitter and is hoping that her recovery would be fast. That said, I'm sure it won't be long until we see her dancing on stage in 20-inch platform heels.
