The 21-year-old 'Wrecking Ball' hitmaker is apparently constantly reminded by her close associates to curb her dramatic behaviour before anyone takes advantage of her acts, reported Contactmusic.
"Engaging in bad behaviour in front of people the way Miley does is like playing Russian Roulette. It is just a matter of time before one of her so-called friends attempts to sell her out," a source said.
The friends of the singer are concerned that someone may share the intimate details of her life in a tell all book.
"As bad as something like a tell-all would be, it could be what helps her to make a change. Her secrets coming out could be what wakes her up before its too late," the source added.
