London: Katy Perry has revealed that the "dark" side of show business troubles her.

The ` Firework ` hit maker told Elle magazine that she feels there`s little she can do to help her famous pals when they are surrounded by the wrong people, the Daily Express reported.

The 28-year-old singer, who was previously married to Russell Brand, revealed she knows a lot of people with the most detrimental entourages, saying they are the root of their demise.

She added that it`s really unfortunate, but you can`t save these people and her days of celebrity saving are over.
