A rapper GRABBED the Biebs by the throat.. and he looked very scared

New pictures have emerged of Justin Beiber being held up by the throat by rapper Post Malone.

Post Malone is supporting Bieber on his Purpose world tour, and while the pair were partying with their entourage in Houston, things became a little heated.

According to the Daily Mail, earlier in the evening Justin used Post's arm "as an ashtray."

Things then became a little heated and Post put his hand around Justin's neck. And let's be honest, Justin looked very startled by the whole thing.

In a video at the club, Malone is seen performing a song, and it is then that Justin stubbed out his cigarette, yet the rapper kept on going. Afterwards, Justin was seen rolling his eyes.

Whether there's bad beef between them, or this is all in good fun, we don't know. But the whole scene looks very serious, so we hope they can sort things out before it gets out of hand.
