Miley Cyrus' eyebrow-raising, sexually-charged antics makes many wonder how far she is willing to go and when it will ever stop. Her worried godmother Dolly Parton now reveals her concerns for the "Wrecking Ball" singer.

The 68-year-old country singer explained that Cyrus has been trying so hard to get rid of her good girl image. "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,'" said Parton. "I think she felt she had to make that severe change. And she obviously did."

"I'm hoping that she holds it in the road and doesn't do so many things that are that bizarre," she added. "I don't think the crowd would be so forgiving again if she did anything else that was really offensive. I don't want it to overshadow her talent."

Dolly Parton, who has been a good friend of Billy Ray Cyrus for years and was chosen to be the "Adore You" singer's godmother, said that she is shocked and "very worried" by her nonchalant attitude towards drug use.

Miley Cyrus has previously admitted to trying cocaine and enjoying marijuana. "I think weed is the best drug on earth. One time I smoked a joint with peyote in it, and I was a wolf howling at the moon," she said. "I really don't like coke. It's so gross and so dark."

Cyrus has postponed her U.S. Bangerz tour until August due to her illness.
