Chris Brown has released a remixed, freestyle rap version of Kanye West's "Theraflu" that appears to contain a major swipe at ex-girlfriend Rihanna.

The R&B singer, who collaborated with Rih earlier this year, raps, "Don't f--k wit my old bitches ... like a bad fur ... every industry n!gga done had her."

"Trick or treat like a pumpkin ... just to smash her."

Are we reading too much into it? Listen and see:





Hours after Brown released the track, Rihanna stopped following Brown on Twitter, a move fueling peculation that the above lyrics are about her.

A short time later, Brown unfollowed Rihanna.

The two have been rumored to be hitting it for some time, despite his assault on her in 2009 ... but he's also been dating Karrueche Tran.

So, yeah. That about sums it up. What do you think? Is Chris dissing his ex? Should she never talk to him again? Does anyone care? Comment below!
