The legend of the real "Billie Jean"

There are contradictory claims as to what the song's lyrics refer. Some believe that they are derived from a real-life experience, in which a mentally ill female fan claimed that Jackson had fathered one of her twins. Others, pointing to the fact that Jackson was an avid tennis fan, believed that the song was about tennis great Billie Jean King; however, King's sexual preferences since 1968 render implausible any contention that the song's narrator, who claims to have had both a romantic encounter with Jackson and a child resulting from that encounter, was modeled on King. Jackson himself, however, stated several times that "Billie Jean" was based on the groupies he and his brothers encountered while part of The Jackson 5. 

^{Jackson biographer, J. Randy Taraborrelli promoted the theory that "Billie Jean" was derived from a real life experience the singer faced in 1981. The Magic & The Madness documents how a young woman wrote Jackson a letter, which informed the singer that he was the father of one of her twins. Jackson, who regularly received letters of this kind, had never met the woman in question and ignored it. The woman, however, continued to send Jackson more letters, which stated that she loved him and wanted to be with him. She wrote of how happy they would be if they raised the child together. She pondered how Jackson could ignore his own flesh and blood. The letters disturbed the singer to the extent that he suffered nightmares."Billie Jean" is kind of anonymous. It represents a lot of girls. They used to call them groupies in the '60s." He added, "They would hang around backstage doors, and any band that would come to town they would have a relationship with, and I think I wrote this out of experience with my brothers when I was little. There were a lot of Billie Jeans out there. Every girl claimed that their son was related to one of my brothers.}

Following the letters, Jackson received a parcel containing a photograph of the fan, as well as a letter and a gun. Jackson was horrified—the letter asked that the pop singer kill himself on a certain day and at a specific time. The fan would do the same once she had killed their baby. She wrote that if they could not be together in this life, then they would be in the next. To his mother's dismay, Jackson had the photograph of the woman framed and hung above the dining room table of their family home. Afterward, the Jacksons discovered that the female fan had been sent to a psychiatric hospital.
