Justin Bieber

I don't get the whole, you know, demonic thing

Justin Bieber has opened the door to a collaboration with controversial hip-hop star TYLER, THE CREATOR - but warned he will only work with the rapper if he cuts out his cussing.

The Odd Future frontman revealed last year (11) that he's a fan of the Baby hitmaker and insisted he wanted to duet with Bieber on a "'90s R&B" track with "break beats, hard drums (and) pretty chords".

Now Bieber has spoken out to confirm he's happy to collaborate with his pal, but only if he tones down his expletive-filled lyrics.

Bieber tells Britain's Q magazine, "I don't know if I really agree with all the music that he does. And he knows that - he's my boy. He's a friend of mine. I don't get the whole, you know, demonic thing. If I did do something, he'd have to do clean. I'm not going to do a dirty song with him!"
