Michael Jackson has been hit with a $1 billion lawsuit from a woman called Bille Jean - who reportedly wants custody of his son.

In a suit filed in Los Angeles on Wednesday, Billie Jean Jackson alleges she is the mother of the singer's son Prince Michael Jackson II, nicknamed Blanket.

The woman demands $1 billion in support payment, as well as joint legal and physical custody of the six-year-old, according to legal documents obtained by U.S. news programme Extra.

Billie Jean also requests visits with the boy on Fridays, Saturdays and Sundays - in addition to participation in Blanket's education.

Jackson refused to identify Blanket's mother after he was born in 2002, but has previously said the child was the result of artificial insemination from a surrogate.

He has faced similar lawsuits in the past. In 2006 and 2007, a woman unsuccessfully sued him for paternity payments, claiming she helped Jackson reproduce.
