O.J. Simpson has reportedly agreed to submit himself to a paternity test to see if Khloé Kardashian is his daughter, but there's a catch. According to a report from the Daily Mail, Simpson will only agree to the test if she comes to visit him at the Lovelock Correctional Center in Nevada, where Simpson is currently serving a sentence of 9 to 33 years for an armed robbery conviction in 2007.

"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."

Felix also claims Khloé previously "begged" Simpson to take the test.

Rumors of Simpson being Khloé's father have persisted for years, despite many impassioned retorts from the Kardashian fam. In April, surrounding the hype of FX's American Crime Story: The People v. O.J. Simpson, Kardashian Dynasty author Ian Halperin claimed he once penned a letter to Simpson in hopes that the two could meet and discuss the rumors. "If I could establish his trust, my goal would be to have him at least admit that he had an affair with Kris Jenner back in the day," Halperin told In Touch Weekly. That meeting never happened.

In 2012, TMZ obtained a copy of a statement from the late Robert Kardashian in which the famous attorney said Khloé was indeed his daughter. According to Felix, who once penned a book of his own entitled Guarding the Juice, O.J. wants Khloé to "show him a little respect" by paying him 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."
