On September 4, Rihanna mocked Chris and Karrueche's relationship, writing, "There's a difference between having a real relationship and just being together because that's all you're used to. There's a difference between meaning your 'I love yous' and just saying them every night because 'that's what you do'. There's a difference between being together and wanting to be together. It's a relationship, not a routine." (FameFlynet)

Our society is full of rappers (which I listen to) who have sold drugs (poisoning)... But yet we glorify them and imitate everything they do. Then right before the worlds eyes a man shows how he can make a Big mistake and learn from it, but still has to deal with day to day hatred! You guys love to hate!!! But guess what???" (SplashNews)
