Dolly Parton had been telling fans that she was ill, that she had suffered from kidney stones that were keeping her sidelined, but as we all now know, there was more going on than that. Dolly’s passing came after a very private battle with cancer, and fans are wondering why the singer had kept that diagnosis under wraps. Jada Star, Dolly’s niece, explained that to “Extra.” “We kind of kept all that stuff real private,” Star said of the illness. “She never wanted to worry anybody. So I think it was just a shock on Tuesday.”
