Don't Let The Smooth Hair Fool You! Justin Bieber Hangs Up On Radio Host! (AUDIO)

If you didn't know before you know now! Don't mess with the Biebs!

Justin Bieber recently did a phone interview with Mojo In The Morning, and things didn’t exactly go as smoothly as planned by the radio show!

The interview started out pretty normal, until the DJ compared him to Justin Timberlake for his new song “Boyfriend,” which didn’t sit too well with the Biebs.

As things seemed to get more awkward after Justin was clearly getting aggravated, the DJ took it to the next level and talked about his mother.

The host brought up how Harry Styles of the group One Direction has been dating older woman, and asked whether Justin was concerned about him going after his mother.

That’s a definite no-no!

Justin didn’t need to hear anymore and hung up after taking a quick shot back at the DJ.

We don’t blame the Biebs for hanging up in that situation.

Perhaps the teen sensation is taking notes from Nicki Minaj and her Hot 97 incident. Sometimes you just have to demand some respect, right?

Do you guys think Justin was right for hanging up?
