Saturday night, from the depths of his subterranean cave, teen idol Justin Bieber took revenge on someone (who seems to be a minor so we're not going to bother naming names) who had allegedly hacked the Twitter account of the star's childhood friend. How best to get back at someone who has wronged you in your world 2.0? By Tweeting their phone number to your four and a half million followers, of course! We've seen this nerd fleeing throngs of girls on a Segway in the past -- which made him seem rather cool in our eyes -- but now we must ask ourselves... is Justin Bieber as innocent as he appears to be? Either way, nice burn.
