Beiber Tweets Foe's Phone Number Today in the world of gossip you only know about if you're 13 By Evann Gastaldo, Newser Staff Posted Aug 16, 2010 8:20 AM CDT 16 comments Comments In this June 24, 2010 file photo, Justin Bieber performs in Trenton, N.J. (AP Photo/Tim Larsen, File) (Newser) – Justin Bieber seems so sweet and adorable, right? But he is apparently not above tweeting an enemy's phone number to his 4.5 million followers. Gawker reports that the foe in question, teen Kevin Kristopik, allegedly hacked the Twitter account of one of the Bieb's childhood friends and got Justin's phone number from it. In an apparent attempt to get payback, Bieber tweeted Saturday: "everyone call me 248-XXX-XXXX :) or text," but the tweet was removed after a few minutes. That was still enough time for thousands of Bieber's followers to retweet, causing Kristopik to receive quite a few calls and more than 10,000 text messages (he tweeted a video of his phone going off, before deleting his Twitter account entirely). Kristopik's reaction: "@justinbieber is a dick. i still like him, but this was so low." Still not quite sure exactly who Justin Bieber is? Click here.
