The woman claiming to be Michael Jackson's illegitimate daughter is getting shut out by the woman she claims is her mother, Diana Ross's sister - Dr. Barbara Ross-Lee.

Speaking to TMZ, Dr. Ross-Lee said that Mocienne Petit Jackson "is not my daughter" and she also added that Petit Jackson is "delusion" and that the situation is incredibly "bizarre".

Diana Ross's sister also adds that the story can't be true because if Petit Jackson was conceived in 1975 as she claims, then it would be impossible as Ross-Lee hadn't even met the King of Pop.

Dr. Ross-Lee also added that she recalls a time when Petit Jackson "was really harassing me at my office", and this led to the police being called. She does however say that she responded to Petit Jackson's email a few years ago, but told her that she was mistaken and she wished her well.

According to TMZ, Petit Jackson has filed legal documents asking for the court to grant her a DNA test to prove that she is Michael Jackson's daughter.

Randy Jackson, one of Michael Jackson's brother has said the situation "sounds kinda crazy."

Wowza. Can't wait to hear court judgement on this one
