The family of Diana Ross are strongly challenging claims that the late King of Pop Michael Jackson fathered a love child with one of their clan.

Mocienne Petit Jackson may not even be the soul singers niece - her supposed mum Dr Barbara Ross-Lee claims she is not the girls mother and that she never even met Michael Jackson.

Mocienne filed court papers in LA earlier this week claiming that she was the result of a one night stand that occurred between Diana Ross's sister Barbara and a then seventeen year old Michael Jackson in 1975. The legal action aims to force the Jackson family to allow a DNA test to take place so to prove (or not) Mocienne's claims. If her claims were proven true, then she would subsequently sue for a cut of the Jacko estate.

However, Jackson Junior's paternity claims have been hindered somewhat by Barbara Ross disputing the maternity claims that seem to be taken as a given in the legal papers. That is to say Diana Ross's older sister says she is not the mother of the claimant.

"Bizarre"

What's more Barbara Ross-Lee claims that Mocienne has been harassing her for some time, that she has made it clear to her that she is not the woman's mother, and that the latest story about her father being Jacko is "bizarre" and totally made up.

Certain aspects of Mocienne's lawsuit seemed somewhat outlandish even before Barbara Ross denied having any connection with the claimant. In particular, the legal papers claim that Michael Jackson's mother Katherine conspired to keep her son's alleged love child a secret by attempting to abduct Mocienne, and then bumping off the people involved in the failed kidnap.

The Jackson family are yet to comment on the lawsuit, while Mocienne is yet to comment on Barbara Ross's statement.
