"Billie Jean" is a song by American singer-songwriter Michael Jackson, released by Epic Records on January 3, 1983, as the second single from his sixth studio album, Thriller (1982). It was written and composed by Jackson and produced by Quincy Jones and co-produced by Jackson. "Billie Jean" blends post-disco, R&B, funk, and dance-pop. The lyrics describe a woman, Billie Jean, who claims that the narrator is the father of her newborn son, which he denies. Jackson said the lyrics were based on groupies' claims about his older brothers when he toured with them as the Jackson 5.
