Chris Brown is like a bad case of the flu - Rihanna just can't seem to shake him. But despite their violent history, the former lovebirds recorded two tracks together back in February - once that pesky restraining order expired, of course. It seems that the "Umbrella" singer is on the skids again with the convicted felon, however. Brown recorded a remix of Kanye West's homage to Kim Kardashian, "Theraflu," and he kind of got the whole love song thing wrong. With lyrics like, "Don't f**k with my old b*tch it's like a bad fur/Every industry n**ga done had her/Shook the tree like a pumpkin just to smash her/B*tch is breaking codes, but I'm the password." Rihanna reacted by unfollowing Brown on Twitter, but not before she wrote, "Aw, poor dat #neaux1currrrr [no one cares]" Brown lashed out as well - only not with his fists, for a change. He wrote, "Assumptions! I didn't say any names so if u took offense to it then its something you feel guilty about," and followed up the tweet by unfollowing Rihanna. In other words, Brown has gained perspective and maturity from his past mistakes. Not.
