Former label mates take shots at each other over Twitter, during a beef session started by Slim the Mobster.

50 Cent was quite active on the Twitter beef front this past weekend, first taking shots at Rick Ross' lacking concert crowd, and then responding to jabs from Slim the Mobster. 

Slim the Mobster, a former Dr. Dre protegee, seemed bitter when he tweeted about 50 Cent, alleging the rapper stole his style and music. 

Slim went on quite the rant against Fif, calling him gay, a snitch, saying he stole his swag, even adding some photos along with his tweets. He took shots at 50's new artist Paris as well.

"You got dropped twice b4 marshall saved you let's not forget u can't walk your block without getting sweated by radimez @50cent," Slim tweeted.

Slim's string of tweets included, "Dre didn't drop me I got tired of being hated on by @50cent I asked to be let go ....."

50 responded to Slim, although his tweets didn't go on for quite as long, he said, "Yo what's that boy name,DRE Dropped him off after math he got a big ass A on his back LMAO."
