Rihanna has reportedly been sued for a second time over claims that she plagiarised parts of her 'S&M video. The 'Man Down singer is facing a legal challenge from photographer Philipp Paulus for allegedly 'exploiting a series0 of shots from a collection of his dating back to August 2010. Paulus highlighted one segment in particular from the controversial promo - a clip of Rihanna strung up behind a wall of transparent plastic - as being directly lifted from one of his pieces, E Online states. Why a worldwide celebrity is not able to afford a creative director, who creates individual concepts and stagings, is incomprehensible to me, Paulus argued. To create new things within the creative cosmos, you can only expect this to come from a real genius; there is no doubt about that. However, in this case there is no real genius who created their own work; instead they stole ideas from a creative talent. DS
