NEWS: Justin Bieber Tweets Hacker's Phone Number

Justin Bieber has reportedly tweeted the phone number of a US teenager after the boy hacked into the account of a friend of the singer. Bieber is alleged to have published Kevin Kristopik's mobile phone number on Twitter, encouraging his followers to call up the phone.

He is alleged to have written: "Everyone call me [phone number removed] :) or text."

Kristopik also allegedly tweeted in response to the incident, although his account has now been deleted.

Regarding Bieber, he is said to have written: "I never asked for it, @justinbieber is a dick."
