Lil Wayne has some serious beef with Justin Bieber‘s longtime manager Scooter Braun.

Weezy recently released a video threatening Braun for talking smack to the media about his Young Money artist Lil Twist.

According to various reports, Braun has blamed Bieber’s destructive behavior on Lil Twist and labeled him as a bad influence in Bieber’s life. Twist eventually moved out of JB’s Calabasas home over the drama.

In the footage above, Wayne fires back at Braun in defense of his “brother” Twist:

“This my nigga Twist right here. I heard that they got a bitchass nigga named Scooter that be running with my little brother Justin Bieber … I heard this bitchass nigga Scooter talkin’ shit about my little brother.

“Nigga this my motherfuckin’ brother, anything you got to say, when you see me say it to my motherfuckin’ face. And if you do happen to say it to my motherfuckin’ face, I ain’t gonna make you eat them words nigga, I’ma put them bitches on your tombstone.”

Weezy ends his profanity-laced rant with, “We just came back from France WITH my lil’ brother Justin Bieber,” and a stern message to Mr. Braun: “Fuck you, Scooter!”

Yeah… We think Scooter may want to apologize ASAP or just avoid Lil Wayne altogether for the rest of his life, though an apology would be much easier.
