Khloe Kardashian and her paternity have been the subject of scrutiny several times in the past. Several sources claim she’s not really Robert Kardashian Sr.’s biological daughter.

After slamming allegations several times in the past, it seems that Khloe is considering this as a possibility and is seeking that help of OJ Simpson in figuring out who her real father is.

Khloe’s paternity was once again brought to life after The Reelz documentary titled Kardashian: The Man Who Saved OJ went on air. The story revolves around Robert Kardashian, who defended Simpson during the 1995 murder trial.

According to CBS, a guard who watched over Simpson at Lovelock Correctional Center in Nevada was interviewed for the documentary, during which he shared some interesting details about the Kardashian family.

The guard, named Jeffrey Felix, said Khloe Kardashian once begged Simpson to take a paternity test to find out if he’s her father. The former sports star is allegedly willing to take the paternity test on one condition—that she personally visit him and “show him a little respect.”

The Daily Mail reports Simpson will agree to take a mouth swab to provide the necessary DNA sample to proceed with the test. Felix further revealed that jail authorities have given permission for Simpson to proceed with the test.

“It’s just a quick mouth swab and they would allow it to happen during a visit,” Felix said. “He wants to talk to her about some other things too, but more importantly like her he wants to know if she is his daughter.”

Questions about Khloe’s paternity stemmed from a 2009 episode of Keeping Up With The Kardashians where the star talked about possibly being adopted. Following her statement, Jan Ashley, Robert Kardashian’s wife after her split with Kris Jenner, claimed that the defense attorney confided in her and said that “Khloe is not really a Kardashian.”

Another wife, Ellen Kardashian, said Khloe Kardashian constantly thought she was adopted as a kid. “Khloe brought it up all the time,” Ellen said. “She looked nothing like the rest. She was tall, had a different shape, light hair, curly hair. Didn’t look anything like the other three children.”
