Rihanna's Twitter feud with Chris Brown's girlfriend Karrueche Tran has gone to absurd levels, with fans now sending death threats to Tran on the social-networking website. According to TMZ, some of the violent tweets read, "I hope Rihanna beat the dog s--- outa yo a--," "Watch yo back" and "I will kill you."

This whole thing may have been started when RiRi posted a photo of a rice cake wearing sunglasses and earrings with the caption, "Ima make u my b----." If you don't know, Tran, who is Vietnamese, ignored the joke, but now she is concerned for her safety.

Sources tell TMZ that after receiving a barrage of violent messages on Twitter, Tran is in fear of her life and refuses to leave the house without Brown's bodyguards protecting her. Like a good boyfriend, Breezy is comforting Tran and is assuring her that she has nothing to worry about.

However, looking at Tran's timeline on Twitter, it seems as if Breezy's boo is unfazed by any threatening messages towards her. When one of her tweeps asked her if she is scared of Rihanna's crazy fans, Tran replied "GTFOH." She also wrote, "Never be afraid to be yourself."

The real lesson here -- stop hating on Twitter and be more productive with your life.
