Rihanna Blasts Chris Brown For Relationship With Karrueche Tran

 Brown has been spending more and more time with ex-girlfriend Karrueche Tran, which seems to be upsetting the Barbadian beauty. Using Instagram to vent, the singer posted several messages on Thursday morning which could be interpreted as being aimed at Brown.
Those messages include: “I have to stop saying, ‘How stupid can you be?’ I think people are starting to take it as a challenge,” and, “How much better would life be if a liar’s pants really did catch fire?”
Rihanna and Brown spent the holidays together, but have since been on the outs. In that time, Brown and Miss Tran have been spotted hanging out in Los Angeles.
