South Korean pop sensation RAIN has been slammed by animal rights campaigners for "dressing like a caveman" and wearing fur. The 25-year-old singer/actor was blasted by People for the Ethical Treatment of Animals (PETA) for failing to set a good example to fans by wearing fur on stage. In an open letter to the star, PETA urged him to stop promoting the animal pelts. It reads, "You have said that you want to show American women 'how sweet and loving Asian men are'. Correct us if we're wrong, but wearing fur is anything but 'sweet' and there is no 'loving' way to rip the skin off a still-twitching animal. "And although you have likened yourself to SexyBack singer Justin Timberlake, you are anything but sexy for wearing the fur of tortured animals on your back."
