Grandmaster Flash Says R. Kelly's His Friend but He's Done Playing His Music

Even R. Kelly's longtime friends are turning on him, like hip-hop icon Grandmaster Flash, who says you won't hear him play a single Kelly hit song from now on.

We got Flash Thursday at LAX and asked him if DJs, in general, should join the #MuteRKelly movement. Little did we know that Kelly and Flash are pals. The Bronx legend told us, "I've been knowing him for a very long time."

Still, he didn't hesitate to say, "I can't play his music." Now, the question Flash really wrestled with was ... what happens the next time he sees his "friend?"

Despite his stance on Kelly's music, Flash says he wouldn't turn his back on him, personally. He has some thoughts on what kinda help Kelly needs.

Now, taking a photo with Kelly??? Grandmaster Flash says that's a different story.
