Mocienne Petit Jackson

*A woman in her mid-30s has come forward claiming she is the illegitimate love child of Michael Jackson and Diana Ross’ sister…and that she’s owed a piece of the King of Pop’s estate.

According to TMZ, Mocienne Petit Jackson filed legal documents with L.A. County Superior Court claiming she was conceived in 1975 when MJ, then 17, secretly impregnated her mother Barbara … who happens to be Diana Ross’ sister.

Mocienne, who now lives in the Netherlands, claims when she was 9-years-old, Michael’s mother Katherine hatched a plan to “abduct” her and send her to Belgium to protect Michael’s “reputation.” She claims all 7 of her abductors were later murdered.

The woman says she is coming forward now so she can “formally claim my part of my father’s inheritance.” She also wants custody of MJ’s kids so she can give them a “more normal life.”

MPJ also claims she was diagnosed with Vitiligo, a skin disorder that Michael shared.
