The document discusses Rihanna as a postmodern artist. It notes that with her large social media presence and willingness to reference controversies in her music videos, she blurs lines between music and celebrity. The document also analyzes her controversial music video for "S&M" which was banned in some countries for its references to BDSM and sexuality. It argues that Rihanna fits the definition of postmodernism by distorting views of what is acceptable and challenging expectations of artists and celebrities.
