Teen idol Justin Bieber slammed the phone down on an interviewer from Mojo In The Morning after certain topics were brought up.

Although the on-air chat started well, things soon went downhill after the DJ admitted that he thought his new album's lead single 'Boyfriend' was actually by Justin Timberlake:

"Man, that's crazy 'cause our voices sound nothing alike. I mean, I'm not trying to sound like anyone. Saying I sound like someone else is not really a compliment."

Later in the conversation, the interviewer brought up One Direction and made a joke about Harry Styles' penchant for older women, asking Bieber if he was concerned at having the boyband member around his mother, Pattie, to which he replied:

"I think you should worry about your mom, bro."

The Mojo DJ then added, "Justin my mom's dead, so unfortunately it wouldn't work" and Bieber swiftly ended the call.
