I don't think any of us really think that OJ Simpson is Khloe Kardashian's father despite what The Enquirer seems to think. I also know that I am pretty sure that Robert Kardashian is not Khloe's dad either. If he was, Kris would have made sure Khloe had taken a DNA test during one of the shows and she would have come out and explicitly said that Khloe was Robert Kardashian's daughter. She never did. Look how fast they all came out and said she is not OJ's daughter, but no one has ever said anything about her not being Robert's dad. I think she looks a lot like the guy that Kris had the affair with that was shown on the show. Were there lots of other guys that Kris Jenner had affairs with that could be the dad? I don't know, but if you are willing to stray with one person than chances are that is not your first or last chance at the rodeo.
