Fans of Perry might expect some ch-ch-ch-changes in the future. "I love what I do, and when I don't love what I do, I'll make a change … I can't be the candy queen forever,” she says. “And I'm not going to be everything to everyone. I can't tell a person when it's time for them to have sex. Or if they should have a cigarette... But I try to live my life with a lot of integrity, and, hopefully, that sends a message."
