No, 16-year-old Justin Bieber isn't walking down the aisle just yet ... but the teen-sensation is jumping off a New Zealand bridge! The little girl magnet let his ultra-fab locks blow in the breeze as he waited at the edge of the Auckland Harbor Bridge.

We have to admit, Biebs has got some big cojones to do this! But is that him screaming in the video during the fall?

Let's hope he didn't strain his precious vocal chords for his performance tonight at South Auckland's Academic Colleges Group Strathallen school.

You go, boy!
