Lil Wayne 'Threatens' Scooter Braun after Lil Twist Diss [WATCH]: Rapper Rants Against Justin Bieber's Manager, 'N*gga This Is My Motherf*ckin' Brother!' [VIDEO]

Rapper Lil Wayne has no problem speaking his mind - especially when it comes to sticking-up for members of his YMCMB crew.

And apparently, Weezy currently has "beef" brewing with Justin Bieber's infamous manager, Scooter Braun.

All because of troublemaker Lil Twist!

The "Knockout" rapper and his posse were returning from France's annual Cannes Film Festival when he went on a major fant against Braun. The entire tirade was captured by DJ Scoop Doo and posted on his official website, Bread Over Bed (on Monday, May 26). Check it out:

Weezy's entire demeanor throughout the clip is pretty threatening. The popular emcee yells into the camera:

"N*gga this my motherf*ckin' brother, anything you got to say, when you see me say it to my motherf*ckin' face. And if you do happen to say it to my motherf*ckin' face, I ain't gonna make you eat them words n*gga, I'ma put them b*ches on your tombstone." 

Obviously Wayne is still cool with Justin Bieber, but apparently Braun better watch his back!

Rumors suggest that Braun thinks Twist is a "bad influence" on the Biebs. The guys got into a pretty heated Twitter "feud" a few months ago. Do Mstars fans agree, considering the trouble both stars have caused when together?
