R. Kelly's Physician Testifies He's Had Herpes Since 2007

R. Kelly keeps finding himself in more legal trouble...

Just a few weeks back, the Feds accused Kelly of sexually abusing teenage boys on top of all the charges he is already facing, and now they are pressing him for something else. 

They called Kelly's personal pysician of 25-years, Kris McGrath to the stand to testify about his treatment of genital herpes since 2007.

Interestingly, Kelly didn't pay McGrath.  Instead, he would invite him to parties, dinners and concerts.

Prosecutors allege that Kelly knowingly infected multiple people with the incurable sexually transmitted disease, and they are out to prove that in court.

Things aren't looking good for the 54-year old Chicago singer.
