Chris Brown Bashes Ex in Vulgar Lyrics, Rihanna Stops Following Him On Twitter (PHOTOS)

This is no way to treat an ex!

While Kanye West gushed about his girl Kim Kardashian in “Theraflu,” Chris Brown went a completely different route in his version, bashing his ex through rather vulgar lyrics.

Though it’s not confirmed that the R&B star, 23, is rapping about Rihanna — who he was charged with brutally beating the night before the 2009 Grammy Awards– the “S&M” singer, 24, did just unfollow him on Twitter.

Chris raps (warning: read lyrics at your own risk):

“Don’t f*** with my old b*****s … like a bad fur … every industry n***** done had her. … Trick or treat like a pumpkin … just to smash her.”

Needless to say, the lyrics weren’t so well received, leading Chris to tweet: “Assumptions! I didn’t say any names so if u took offense [sic] to it then its something you feel guilty about.”

This isn’t the first time he and Rihanna have caused controversy with their music. Despite their physical feud, the former couple decided to collaborate earlier this year on the song “Birthday Cake.”

Rihanna defended her decision to work with Chris on Ryan Seacrest’s radio show, saying, “I reached out to him about doing ‘Birthday Cake’ because that’s the only person that really … it made sense to do the record. Just as a musician – despite everything else – that was going to be the person.”
