Haters s*

Justin Bieber posted a Detroit teenager's phone number to his 4.5 million followers on Twitter in an act of revenge, Gawker reported Sunday.

The tweet, which Bieber posted around midnight Saturday, read, "Everyone call me 248-XXX-XXXX :) or text." The phone number was not Bieber's but the cell phone of Detroit-area teenager Kevin Kristopik.

Bieber was reportedly angry at Kristopik for hacking the Twitter account of one of Bieber's friends and using it to get the star's phone number. Kristopik admitted the hacking, writing, "im the one who hacked ryan and got justins #" on July 27.

Bieber deleted the tweet a few minutes later, but the damage had already been done: Thousands of Bieber's followers retweeted the message, and Kristopik received countless phone calls and more than 10,000 text messages. Shortly after 1:00am, Kristopik tweeted, "Thanks for giving out my #@justinbieber."

Kristopik posted video online of his phone receiving a stream of calls and text messages.Gawker attempted to contact Kristopik for comment, but his voice mailbox was full.
