When you're not around, all they want is your music. They want to see what the next thing is. But when your music is out they just want to talk s**t about you," Cyrus said. She also feels that things become difficult when one is a celebrity. "When you're a worldwide star, everyone sees everything. Lots of people make a video and put it on Instagram, some people might think it's funny but because it's Justin Bieber, it's really bad," Cyrus said. "If it was your friend p***ing into a mop box then you would be laughing, but because it's Justin Bieber, then it's really bad," she added. Cyrus is not the first celebrity to offer words of wisdom to Bieber. Recently, Britney Spears also advised Bieber to be careful about the side effects of fame.
