Lil Wayne Has Words For Justin Bieber's Manager Scooter Braun, And They Aren't Very Nice

Weezy isn't happy.

Justin Bieber and Lil' Twist used to be the best of friends, but the two have seen their fair share of drama over the past year.

In 2013, Twist either moved or was kicked out of Bieber's Calabasas, California home, after Justin and his boys had a series of run-ins with the law. The Young Money rapper was often painted in the media as a bad influence and now his YMCMB boss, Lil Wayne, is ready to take up for his artist -- and he has Beiber's manager Scooter Braun in his sights.

Warning: the following video is not safe for work.

"I heard this bitchass n---a Scooter talkin' sh-- about my little brother," Weezy said to the camera, in a new viral video, with his arm around Twist in a show of solidarity.

The video was shot by longtime Young Money director and documenatrian DJ Scoob Doo, and published exclusively on his website Bread Over Bed on Monday (May 26).

"N---a this my motherf---in' brother, anything you got to say, when you see me say it to my motherf---in' face," an irate Wayne continued. "And if you do happen to say it to my motherf---in' face, I ain't gonna make you eat them words n---a, I'ma put them bitches on your tombstone."

At the end of the 56-second clip Tunechi signs off with a vicious: "F--- you Scooter!"

In November Twist took to Twitter and blasted Braun, accusing him of putting fake stories in the media that were meant to discredit Twist and make Bieber look "squeaky clean."

The drama between Twist and Scooter had seemingly died down, but MTV News has learned that the clip was shot last night, as the YM team landed back home from their trip to the Cannes International Film Festival in France. No word, as to which particular Braun comment set Wayne off; he just seems to be sick of it all.
