Lady Gaga is back in the headlines after admitting to the London Times that she has been tested for lupus. However, the 'Bad Romance' singer wouldn't reveal the results of the tests, saying only, "I don't want anyone to be worried."

"I'm very connected to my aunt, Joanne, who died of lupus," she continues. "It's a very personal thing." The star made news in March when she collapsed on stage during her 'Monster Ball' tour and had to cancel several shows earlier this year due to exhaustion, and many are concluding that the singer may suffer from the condition, which causes heart palpitations, shortness of breath, joint pain, anemia and extreme fatigue.
