The 18-year-old singer said he does not feel famous and he tries to stay grounded despite his tremendous fan following, reported Femalefirst.
"What does that really mean, 'To be famous?' In general, fame can tear you apart, so you can never really feel like you're famous. When people start acting like they're famous, that's when they start losing it," he said.
Bieber, who is dating singer-actress Selena Gomez, said he tries to keep as much of his life private as possible in order to protect himself.
"I don't like giving too much personal information about where I live and the cars I drive. There are a lot of people in this world that aren't good people, and all they need to do is a little research and then they can.
"People hiding in garbage cans overnight to catch pictures of me; crazy things happen. You can't give out too much personal information," he said.
