Preme's Son Goes In On 50 Cent

50 Cent was not happy that Black Mafia Family founder Southwest T posted up with the son of Supreme McGriff, the man who ordered Fif shot years ago.

So he threatened to have the Starz series BMF canceled, costing T and his family money.

Now McGriff's son has commented on the kerfuffle, and he has nothing nice to say about Fif.

"I pulled up in Detroit to give Southwest T the living legends joint with Meech and Preme on it, and everyone started going on.  And then this bozo.  Look it at this bozo," he said of 50 Cent.  "Why are you so mad?  You got everything in the world to be doing right now, and you're worrying about me. Relax man, go have a drink and relax.  It's too hot for this."

Does Fif need to take a chill pill and relax?
