R+B singer NE-YO has blasted ongoing speculation he's engaged in a bitter feud with teen singer Chris Brown. The SO SICK hitmaker, 23, is bewildered by the reports, because he's just announced an upcoming 29-city tour with Brown and the pair are starring together in new film STEPPIN'. He says, "We're not rivals. Chris is actually one of my good friends. We're friends. It's all friendly, there's no animosity whatsoever. It's not anything negative at all."
