London: Teen sensation Justin Bieber says the moment one starts acting famous, he or she starts losing it.
"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."
The 18-year-old singer tries to keep his personal life away from media glare to protect himself.
"I don`t like giving too much personal information about where I live and the cars I drive. People hide in garbage cans overnight to catch pictures of me, crazy things happen. You can`t give out too much personal information," he said.
He added that he dislikes shaving and hopes he keeps his youthful looks for a long time.
"My mom looks pretty young and my dad does, too, so hopefully I will, too," he said.
