Pop star Justin Bieber refuses to dish out too many details about his private life because he once had a person camp outside his house in a garbage can - just to get a photo.

As the third most powerful celebrity in the world, according to Forbes magazine, the Boyfriend hit-maker is used to living his life in the public eye, but, while Bieber does not mind opening up about his music to reporters, he has adopted a more guarded approach when it comes to talking about his personal property - because crazed fans and photographers will stop at nothing to get close to him.

He tells Vibe magazine, "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 (find me)..."

"(I've had) people hiding in garbage cans overnight to catch (pictures) of me. Crazy things happen."

And the 18 year old has every reason to remain tight-lipped about his possessions - just last month a pack of photographers allegedly tailed Bieber's Fisker Karma sports vehicle as he drove along California's 101 Freeway, resulting in a dangerous high-speed car chase. Bieber was pulled over for speeding and the snapper who led the chase was ultimately booked on charges of reckless driving.
