Justin Bieber thinks his fans are 'crazy'

The teenage heartthrob says there is nothing some girls won't do to get close to him and some admirers even hid in a dumpster in a bid to meet their idol.

He said in an interview with The Sun newspaper: 'The Beliebers have done some pretty crazy stuff.

"Last week, the night before I was due to do a show in Germany, four girls went into a dumpster so they could sneak into the building.

"They climbed in and hid. When the guys working on the truck started getting the garbage they found them straight away. It was crazy."

The programme Justin was due to appear on was the German TV show 'Wetten, Dass?' ('You Bet') but he had to cancel after contestant Samuel Koch suffered serious back injuries as he attempted to jump over cars on spring-powered stilts.

The hysteria that surrounds the 'Baby' hitmaker can sometimes be dangerous. Last November some fans were injured in a crush in Long Island, New York, when he appeared at a mall for a show.

The 16-year-old pop star said: "I've had a few gigs where things have got out of hand and there has been a huge crush with my fans. They are important and I don't want them being hurt. They are a mad crowd."

One thing Justin has enjoyed about finding fame is getting to meet his idols, but he insists he always manages to keep his cool when he is introduced to his heroes.

The singer ' who is a huge soccer fan ' said: ' don't get nervous meeting famous people really. I have met David Beckham a few times. He's a nice guy. He came to my show in Los Angeles. His kids were with him. They were nice too."
