It was revealed Friday at San Diego Comic-Con that pop star Rihanna will be joining the cast of ‘Bates Motel’ for it’s fifth and final season. The announcement was made when the show’s official Twitter account tweeted a video of the singer. “I am about to check into the Bates Motel very soon,” Rihanna said in the video. “Guess what else? Guess who’s playing Marion?” The TV series is a prequel to Alfred Hitchcock’s 1960 horror film “Psycho.” In the movie, Marion Crane meets her death in the infamous bloody shower scene. Rihanna will star alongside Vera Farmiga, Freddie Highmore, Max Thierot, Olivia Cooke and Nestor Carbonell.
