Take a listen to the interview with Justin, which starts out pretty light and fun but takes quite a turn, beginning with comparisons of Biebs to Justin Timberlake.
You can tell Justin is agitated by the comparison, and later doesn't seem to want to talk about One Direction (calling them "kids").
Of the Timberlake comparison, Justin said, "Our voices sound nothing alike," adding, "I mean... saying I sound like someone else is not really a compliment."
Justin shuts it down shortly after the interviewer asks, "Do you worry about Harry [Styles] around your mom since he likes older women?"
Justin jokes, "I think you should worry about your mom."
The interviewer responds, "Justin, my mom's dead so unfortunately I don't think that will work."
The interviewer says, "This is the moment of the interview where it goes south."
No kidding. Justin hung up!
It's a mixed bag of reactions to Justin ending the interview, with some thinking he was bratty and others believing he was justified to hang up.
