Mocienne Petit Jackson has filed documents with the Los Angeles County Superior Court stating as she is the offspring of the late `King of Pop` she should receive an inheritance cheque following his death in June 2009.
According to gossip website TMZ, she alleges she was conceived in 1975 when the `Bad` singer impregnated her mother Barbara - who she claims is the sister of soul singer Diana Ross - when he was just 17 years old.
However, Mocienne claims an elaborate cover-up plot was then hatched by Michael`s mother, Katherine Jackson, so the world would never know about the singer`s indiscretion.
She claims when she was nine, Katherine decided to fake an "abduction" of her in the hope of protecting Michael-s reputation.
According to Mocienne - who now lives in the Netherlands - all seven of her supposed abductors were then murdered after taking her to Belgium.
The legal documents state the woman claims she has now been diagnosed with Vitiligo - the same skin condition Michael suffered from - and has launched court action to "formally claim part of her father`s inheritance".
The superstar`s children - Prince Michael, 13, Paris, 12, and eight-year-old Prince Michael II, known as `Blanket` - have been in the custody of Katherine since their father passed away, but Mocienne is seeking to claim legal guardianship of them to give the kids "a more normal life".
This is not the first love child mystery to have surfaced since the pop legend`s death.
In 2009, 25-year-old Norwegian dancer Omer Bhatti was rumoured to be his son, the result of a one night stand between his mother Pia and the `Billie Jean` hitmaker in 1984.
Omer - who lived at the singer`s Neverland ranch for several years - later denied Michael was his biological father, but revealed the singer used to tell him he was "like a son" to him.
