Hannah Montana [SEP] Introduction
Hannah Montana, also known as Hannah Montana Forever in its fourth and final season, is an American teen sitcom created by Michael Poryes, Rich Correll, and Barry O'Brien. It focuses on Miley Stewart (portrayed by Miley Cyrus), a teenage girl living a double life as an average schoolgirl by day and as the famous pop singer Hannah Montana by night, which she keeps secret with only a few people knowing of her alter ego. The story follows the daily life of Stewart, her best friends Lily and Oliver, her brother Jackson, Jackson's arch-enemy Rico and her father Robby (Cyrus' real-life country singer father, Billy Ray Cyrus).
