For years, Khloe Kardashian has been rumored to be O.J. Simpson’s daughter, but the “Keeping Up With the Kardashians” star has always disproved the claims. She always insisted Robert Kardashian was her dad, but a new report claims she recently reached out to O.J. and asked him to take a paternity test.

Daily Mail reports that a prison guard, Jeffrey Felix, overheard a conversation between Khloe Kardashian and O.J. Simpson at the Lovelock prison in Nevada. He claims that O.J. Simpson refused to take the paternity test, which, if true, could be the reason the TV show never displayed any test results.

“It was one of those conversations which involved her paternity,” Jeffrey Felix said. “She was very upset and OJ was trying to calm her down. One day I could hear Khloe screaming on the phone. He said she was upset because she wanted him to take a paternity test because the media is all over him, to see if OJ is her actual dad – and OJ told her ‘no.’”

Many have pointed out that Khloe Kardashian looked different than her other Kardashian siblings. While Kourtney and Kim Kardashian are shorter, Khloe is tall. Also, Khloe’s hair appears to be the curliest among the Kardashian clan. Additionally, the strong Armenian features of some of the Kardashians also seemed to differ slightly from Khloe’s visage.

Robert Kardashian’s first wife and Khloe Kardashian’s mom, Kris Jenner, had always reiterated the fact that Robert is Khloe’s dad. But his third and final wife, Ellen Pierson, said that her late husband had admitted Khloe Kardashian was another man’s child. Robert’s second wife, Jan Ashley, backed up Ellen’s story.

The close relationship of Kris Jenner and O.J. Simpson was the source of all these rumors. They are so close that the former football player was at ease telling her his side of the story when she visited him in jail, trying to convince her that he didn’t murder Nicole Brown Simpson back in 1994, as reported by People Magazine.
