Look up in the sky! It's a bird, it's a plane...no, it's Justin Bieber!
The 16-year-old "Baby" singer showed his fearless side yesterday when he bungee jumped off of New Zealand's Auckland Bridge.
"He was excited beforehand," a source tells us. "He was joking around and dancing. After it was over, he said the experience gave him a buzz."
You won't believe who joined the pint-size pop star for a jump...
