Well I believe Omer is MJ's son. He looks too much like Michael in my opinion. He even has mannerisms like MJ and he has a soft spoken voice like MJ. I think Omer has a right to keep this information to himself. It's only important that MJ knows and the rest of the family if Omer is a Jackson. If he chooses to tell the public then so be it. I found this video where you can even see MJ and Omer have the same exact facial expression.
