After coming 4 hours late to a charity appearance and canceling two shows of her Diamonds Tour, it’s no secret that she’s wearing herself thin–and her doctors agree! They have told her that it may take months for her to fully recover. Anyone who follows her on Instagram know she’s smoking and having a blast always. The source who disclosed it also said, “RiRi’s received death threats, verbal attacks and has fallen out with some of her best friends recently, including Katy Perry. This has taken a huge emotional toll.” The girl has to take care of herself because she’s still got plenty of the tour to go! Check out some pics from her tour in the gallery.
