Celebrity activism, online celebrity, and online activism are all growing areas of research, but have received relatively little integration. This article argues that connected celebrity activism deploys social media to forge a variety of connections, enabling activist values to pervade a celebrity persona, reinforcing perceptions of authenticity and recirculating those values to disparate audiences. In the case of Deaf American actor Marlee Matlin, media reform activism serves as a unifying feature, expressed via technologically-facilitated connections between her acting, activist, and online activities, creating a cohesive star text that is seemingly authentic in respect to both Deaf and celebrity identities without being stereotypical. Such centrality and unification via connected celebrity activism stands in contrast to more traditional celebrity activism, and draws upon the specific dynamics of digital media, online activism, and contemporary celebrity culture.
