”I’m with Meryl”: Celebrity Activism, Self-Presentation and Social Media final version Celebrity activism on social media profiles in the era of the attention economy exemplifies a different dynamic as to how and what the celebrity activist can communicate to fans and followers than previously. Existing research on political activism has primarily concentrated on the representation of celebrity activism in legacy media (Wheeler 2013, Corner and Pels 2003). However in todays attention economy celebrities also address political issues, as well as promoting their philanthropic work and humanitarianism, on their social media profiles. Therefore the aim is to establish a theoretical framework combining theories of celebrity activism with theories of online self-representation and parasocial interaction, as well as theories of celebrity culture in order to be able to analyze how the political is integrated with the personal performance on social media by celebrities. The framworks is apllied to a case study is a selection of six social media profiles belonging to well-known female stars who have been politically active on their social media profile on Instagram: This paper is divided into two sections: 1) The presentation of the theoretical framework combines theories on celebrity activism (Raphael and Lam 2017, Chouliaraki 2013, Drezner 2009) with self-presentation and social media (Marshall 2010, Marwick and boyd 2010, Marwick 2015), celebrity culture (Marshall 1999, Cashmore, 2006, Dyer 1979) and theories of parasocial and mediated communication (Horton & Wohl 1955, Meyrowitz 1985). In the second section this framework is applied to a qualitative empirical analysis of a selection of six profiles belonging to female Hollywood stars including Jessica Chastain, Viola Davis, Charlize Theron, Brie Larson, Kerry Washington and Emma Watson. The analysis focusses on how their celebrity activism fit’s into their overall self-presentation performance with focus on the concepts of ’moral authority’ (Cashmore), ’authenticity’ (Marwick) and ’transgressive self-presentation’ (Marshall) . The three main issues addressed on the profiles include support for the 2017 Golden Globe speech by Meryl Streep (#I’mwithMeryl), The 2017 Womens March and a critique of the Charlottesville Supremacists. Thus this theoretical framework makes it possible to analyze and critically discuss what kind of celebrity activism is being done on social media by female Hollywood stars today within the attention economy.
