Justin Bieber's "All Around The World Documentary" aired on NBC last night, giving fans a look at what it's like to be the Bieber himself. Bieber was filmed traveling 19 cities in seven countries in a span of just 12 days, to promote his latest album "Believe."
Part One of the documentary featured the 18-year-old singer performing, giving interviews and behind the scenes of his concert.

First, the Biebs is in Norway where his promotional concert caused security and safety fears for the thousands of young fans that descended onto the streets of the city to catch a glimpse of the singer. Bieber said: "I guess I'm cool with being a heartthrob. I'm 18 and having a lot of girls like me isn't a bad thing."
He also referred to his experience of being mobbed by girl fans as something the Beatles or Michael Jackson went through.
Next he hits London where he meets Kelly Clarkson and Katy Perry. He continues his Europe tour by heading to Paris, where he sings a French version of "One Less Lonely Girl".
His concussion after he hit a glass wall was also filmed. He performed his track and exited the stage but walked straight into the glass wall. The staff seemed pretty worried and paramedics were called.
Part Two of the documentary will air tonight (June 21).
