“Billie Jean” is a song by the American recording artist Michael Jackson. It is the second single from the singer’s sixth solo album, Thriller (1982). It was written and composed by Jackson and produced by him and Quincy Jones. There are contradictory claims to what the song’s lyrics refer to. One suggests that they are derived from a real-life experience, in which a female fan claimed that Jackson had fathered one of her twins. However, Jackson himself stated that “Billie Jean” was based on groupies he had encountered. The song is well known for its distinctive bassline and Jackson’s vocal hiccups. The song was mixed 91 times by audio engineer Bruce Swedien before it was finalized.
