Lady Gaga is having to take extra care of herself on tour as she's tested 'borderline positive' for the disease which killed her aunt, lupus.
The 'Alejandro' singer has suffered a number of health problems recently from headaches to black outs and was tested for the disease.
Gaga says that isn't currently suffering from the condition but doctors have ordered that she needs to look after herself to stop any symptoms flaring up.
Gaga was seen in a pre-recorded interview with Larry King on his U.S. chat show last night and she explained:"Lupus is in my family and it is genetic. My mother told me the other day that my fans were quite worried about me because I did talk about the fact that I was tested for lupus. The truth is I don't show any signs, any symptoms of lupus. But I have tested borderline positive for the disease.
"As of right now I do not have it, but I have to take good care of myself."
