"I am the biological mother of Prince Michael Jackson II (Blanket) and all of his siblings. I am also legally married to the father, Michael Joseph Jackson, who is now deceased. & am engaged to Prince Michael Jackson II's biological father," the petition stated.

Chris Caputo, to whom she claims she is now engaged and says is the biological father one of Michael's babies, tells OK! that he has no ongoing relationship with Claire.
