Is Michael Jackson the biological father?

US Magazine’s sources say that Michael Jackson is not the biological father. Even though Michael was married to Debbie Rowe, the real father is Arnold Klein. He is Jackson’s LA based dermatologist.
Sources say Debbie and Michael signed an agreement that the biological father would never be revealed. Debbie Rowe in 2002 said she carried the children as a personal favor to Michael. Debbie Rowe never revealed if the marriage was ever consummated.

My belief is that their marriage was never consumated.I also believe that none of those childre are his. I hope that Debbie Rowe gets full custody.
