Maybe the best thing to do is actually wait until the results are published by a credible source.
Or maybe multiple sources.
One thing leaped out at me reading that story and that was the parentage of the two oldest children. When I saw their pictures online the first thing that occurred to me was neither had "black" attributes. Nor did either look as if they were offspring of a mixed union. Looking at even more recent photos of both kids is further proof.
I don't know what to think but if MJ was not the bio father things might start getting really ugly when the issue of who raises them comes up.
