Parton expressed concern with the drastic change in behavior she's seen in the younger singer.
Cyrus has done a near-complete 180 from the sweet, innocent character she played on the Disney Channel.
“I hoping that she holds it in the road and doesn’t do so many things that are that bizarre,” Parton said.
“I don’t think the crowd would be so forgiving again if she did anything else that was really offensive,” Parton said. “I don’t want it to overshadow her talent."
“One day, she’d had enough and told me: ‘I need to murder Hannah Montana in order for people to accept who I really am,” she added. “I think she felt she had to make that severe a change. And she obviously did. I was very worried. I was holding my breath, hoping that people didn’t totally crucify her.”
