Lena Dunham is a modern celebrity and television producer-writer who is important in her willingness to self-identify as a feminist, and to engage in feminist activism on social media and in her memoir writing. Her writing in her successful television series, Girls (2012-17), has already raised questions of authenticity. This article develops this analysis further by considering how Dunham's situation, as a transmedia author, complicates this authenticity, particularly through her construction of 'affective ordinariness', a key aspect of her identity as a feminist activist. Her various personas, including that of the celebrity feminist, highlight the 'contradictions' which exist within the current complex culture of postfeminism and the perception of new feminisms. Nowhere are these contradictions more apparent than in the dissonance created by Dunham's transmedia voice in the matter of rape and sexual violence.
