For over a decade, there have been rumors that Robert Kardashian was not Khloe Kardashian's biological father. Instead, a conspiracy theory suggests that O.J. Simpson was her father.

It all started when rumors surfaced that Kris Jenner had an affair with O.J. Simpson while she was married to Robert Kardashian. Jenner and Kardashian were very close to O.J. Simpson and even stood by his side during his trial where he was allegedly accused of murdering his wife, Nicole Simpson.

The rumors have gone on for so long that they have caused Khloe to address them. The "Stronger Looks Better Naked" author has even joked about the rumors on Keeping Up With the Kardashians, but the family has continuously ignored it and assured her that she is indeed a Kardashian.

While the Kardashians have shared their thoughts on the outrageous rumor of Simpson being Khloe's father, Simpson never came forward to state whether the allegations were true or false.

Is Simpson Going To Be A Grandfather?

Finally, after years of waiting on a confirmation from Simpson, TMZ caught up with the former football running back.

Juice finally addressed the conspiracy theory if he's Khloe's biological father. A photographer asked Simpson if congratulations were in order for him regarding Khloe's pregnancy, as she is expecting her first child with her boyfriend, Tristan Thompson.

Simpson clearly understood that the photographer was implying that he was the grandfather of Khloe's child.

"Well, for Bob, God Bless his soul, yeah. I don't know for me. I don't think for me I have nothing to do with it," Simpson said.

Although the athlete denied the rumors, he stated that Khloe and the girls were always nice and that he was happy for them.

"I'm happy for them. Congratulations to her. But trust me, I have nothing to do with it. I would be proud if I had anything to do with it, but I don't," he said.

Baby On The Way

While Simpson is denying the rumors that he will be the grandfather of Khloe's baby, the Revenge Body star is gearing up for her baby.

In an interview with Ellen DeGeneres, Khloe stated that she does not know the gender of the baby, but she does have a few baby names in mind.

"If it's a boy, I'll go with Junior...Tristan Jr. For a girl, I don't even know where to begin. I think I want a K or a T," Kardashian said.

Kardashian is currently six months pregnant and will reportedly give birth sometime in the spring.
