The National Enquirer is reporting that O.J. Simpson is making claims that Khloe Kardashian, sister to Kim Kardashian, is his daughter.

“O.J. believes Khloe is his natural-born daughter through his affair with Kris Jenner when she was married to his buddy Robert Kardashian – and he wants to do something about it,” revealed an insider. “At 65, he’s tired and becoming increasingly aware he may not ever leave prison alive. He says he wants to ‘do the right thing.’”

O.J. has reportedly even included Khloe in his updated will, while removing daughter Arnelle Simpson, whom Simpson claims was blowing all his money and NFL pension checks.

Supposedly, the former football star-turned actor caused a firestorm among family members when they learned he allegedly included Khloe Kardashian in his will, while removing Arnelle Simpson, 43.

The Kardashian clan has denied the rumor on Twitter but it’s not the first time the paternity of Khloe has come to the surface.

Earlier this year her father’s former wife, Jan Ashley, who married the late Robert Kardashian after his divorce from Kris (Kardashian) Jenner, claimed that Robert had told her before his death that Khloe was not his daughter.

“Khloe is not his kid – he told me that after we got married,” Ashley told Star. “He just kind of looked at me and said [it] like it was a matter of fact. He said, ‘Well, you know that Khloe’s not really a Kardashian, don’t you? And I said … ‘OK,’ and that was it.”

Did Kris Jenner stray with O.J.? She confessed in her memoir to having strayed during her marriage to Robert.

Of course Robert notoriously defended O.J. as one of his lawyers in his defense of killing Nicole Brown Simpson and Ron Goldman.
