Tall, with light and wavy hair, fairer complexion, and with a different body build - Khloe Kardashian always seemed like the odd one out when it came to the Kardashian siblings. So much so that rumors have always swirled about with regards to her paternity. 

Back in 2012, Robert Kardashian's ex wives Jan Ashley and Ellen Pierson came forward claiming that Robert Kardashian had explicitly mentioned that Khloe was not his child. But because he was such a great man, and loved her just the same, he never bothered with taking a DNA test. 

According to Ashely, Kardashian simply said, "Well, you know that Khloe's not really a Kardashian, don't you?" He went on to share that he and Kris Jenner were not sleeping together when Khloe was conceived. It's been long rumored that Robert Kardashian's close friend, O.J. Simpson was Khloe's father, but over the years speculation that it could have been former LA Heat soccer player, Todd Waterman.

If people weren't gossiping about Waterman, they were talking about Jenner's hair stylist, Alex Roldan, who Khloe does share a striking resemblance with. In 2012, Kylie Jenner even tweeted a photo of Khloe and Alex Roldan, with the caption: "First official photo of my sister and her dad! Like father like daughter!"

Whether or not Roldan is Khloe's biological father, more and more people have been coming out of the woods to say that Robert had indeed confirmed that Khloe was not his "blood daughter". Apart from Robert's two ex-wives, his pastor, Kenn Gulliksen, and his two best friends, Joni Midigal and Larry Kraines have also spoken out. 

The three pretty much repeated what Ashley had mentioned, but this time, Gulliksen said that while Robert refused to name names as to who was Khloe's biological father, he was reassured that it was not OJ Simpson. 

Whether or not we will ever get to find out who Khloe's real father is, its no surprise that the only men that the reality star has recognized as father figures are both Robert Kardashian and Caitlyn Jenner, formerly known as Bruce Jenner. The two have undeniably played huge roles in her life, and when the former passed away, Khloe found it so difficult to deal with that she couldn't even bring herself to visit his tomb stone.
