Chris “Mac Daddy” Kelly, half of Kris Kross, the nineties teen duo that gave us “Jump,” was found dead in his Georgia home on Wednesday afternoon. He was 34. The cause of death is currently unknown; an autopsy is scheduled for Thursday. Kelly and his bandmate Chris Smith were discovered at an Atlanta mall by Jermaine Dupri, going on to record three studio albums between 1992 and 1996.
