Justin Bieber hangs up on interviewer after Harry Styles question!

A Radio station was left trying to fill air-time on Thursay morning when pop sensation Justin Bieber hung up on an interviewer after he'd made a joke regarding Harry  Styles and the Boyfriend singer's mother, awkward.

Thomas Carballot, the DJ conducting the interview, was asking the singer about his friendship with One Direction when the conversation turned slightly sour. It's no secret that Harry is attracted to the more mature woman and when Bieber described the boys as "good kids", Thomas saw his chance to make the gaff about womanizer Harry and the solo star's mum, saying,
"Do you worry about Harry around your mum, since he likes older women?"
Bieber, sounding caught-off-guard asked the DJ to repeat the question and then replied with,
"I think you should worry about your mum, though" To which Thomas responded that his mother was dead, very awkward.
The interview was then cut short as Bieber hung up. When questioned the singer's management company revealed that the star was "a little upset" about the slight towards his mother, but added that he did make numerous attempts to reconnect the call (Hmm).
However, after speaking to Justin for a second time, the stated that he would "probably not" call the station back (sounds more like it).
