The rumors that set the internet ablaze has now been confirmed. Rihanna has featured chris brown in her new single Birthday cake remix like wise Chris has featured Rihanna in his new song turn up the music remix. This comes after 3 years after chris assulted rihanna. There is no official link yet but you can get the tracks in their respective twitter @Rihanna and @Chrisbrown . I think this move might destroy her career cuz most of her fans were against it. Even billboard wrote her a letter.
