Justin Bieber Tweets Nemesis's Phone Number

Justin Bieber recently when on a little bit of a revenge-streak after a young fan, aka Kevin Kristopik, hacked into his friend's twitter account in order to get Bieber's number. Bieber, none too pleased with the scenario, then revenge-tweeted Kristopik's own phone number -- resulting in Kristopik receiving more than 10,000 text messages in approximately 2 hours (keep in mind that Bieber has like, 4.5 million twitter followers).
