ESPN's five-part documentary on O.J. Simpson titled, "O.J.: Made in America," is sweeping the nation right now and anything to do with the former NFL running back is making headlines, including the possibility that he sired Khloe Kardashian.

The rumors about O.J. being Khloe's real father have been around for years and O.J. is apparently willing to put an end to it once and for all, under one condition- Khloe has to "show him a little respect" and visit him at Lovelock Correctional Center in Nevada.

"She has to go there and talk to him," Jeffrey Felix, a former Lovelock prison guard, told the Mail Thursday. "He wants her to come out to Lovelock and visit him in person. O.J. will do it, and the prison officials have told him they will allow it. It's just a quick mouth swab, and they would allow it to happen during a visit."

"He wants to talk to her about some other things too," he added, "But more importantly, like her, he wants to know if she is his daughter."

That same prison guard also alleges that Khloe has begged O.J. to take the test in the past. Knowing the Kardashians though, there's no way they'd allow this to go down without their camera crews filming it every step of the way. 

O.J. is currently serving a sentence of 9 to 33 years for an armed robbery conviction, but he could be released as early as next year.
