Justin Bieber reportedly took offense to Lil Twist's rant about his manager, Scooter Braun, says a friend of the pop star. Bieber was already slowly cutting Twist out of his life, but the tweets were "the final straw," reports Gossip Cop.

"Justin and Scooter are family," Bieber's pal tells Gossip Cop, adding, "but Twist took it too far this time."

As Beliebers will know, Scooter Braun was the man who spotted Justin on YouTube and went on to make him a star. But it would seem that Twist is not very impressed with his style of management.

In a expletive-filled and cryptic rant, he appeared to be accusing Scooter as portraying him as a bad influence on Biebs.

"Ima keep it 1,000,000 the media drove me away from "social media" ... Not saying they drove me away from my core fans but the s**t some ppl are entertained by ... isn't the real s**t," Twist wrote." "It's been people I've surrounded myself with that's put false information out to help their side stay squeaky clean... And I took that... But with that being said.. F**k u Scooter and everything u stand for.. And all yo fake stories."

The source added to Gossip Cop: "Justin's saddened it ended like this, but you don't cross the line with family."
