'A Milli' rapper Wayne has taken Twist under his wing since he was forced out of his friend Bieber's mansion last year, and they claim the young star's manager has been trying to deflect blame for his artist's bad boy behaviour onto the rising rap star.
In the video, published on Breadoverbed.com, Wayne says: ''I heard this bitchass n***a Scooter talkin' s**t about my little brother.
''N***a this my mother******g brother, anything you got to say, when you see me say it to my mother******g face. And if you do happen to say it to my mother******g face, I ain't gonna make you eat them words n***a, I'ma put them bitches on your tombstone.''
During the clip, Wayne has his arm around Twist in a show of solidarity. He ends the video by saying: ''F**k you Scooter!''
Twist has previously voiced his disdain for Braun, writing on Twitter in November last year: ''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 (sic).''
Scooter was said to have put his foot down over Twist and demanded Bieber sever ties with him in August last year after he was accused of grabbing a girl and holding her against her will at the singer's California mansion. He was later cleared of the charges.
Last year Twist was also pulled over for speeding in Bieber's Ferrari as well as being arrested for Driving Under the Influence.
