The identity of Khloe Kardashian’s biological father is one of the most notorious topics of gossip surrounding the publicity-hungry Kardashian family, with many believing it’s really football star-actor-accused wife-killer O.J. Simpson. Of course, her mother Kris Jenner maintains that the late Robert Kardashian Sr. was her daughter’s real father; but seemingly endless stories continue to run about the true paternity of Khloe. Most recently, Simpson’s manager Norman Pardo said Kardashian “could be” the man's daughter.

The truth “is going to come out sooner or later,” Pardo told In Touch Weekly in a new interview about Simpson supposedly being the 29-year-old’s biological dad. "Khloe could be O.J.'s kid."

But Simpson, 66, who is currently serving a nine-to-33-year sentence in a Nevada prison for kidnapping and robbery, doesn’t seem to think much of the rumor. “Whenever I bring it up, he giggles,” Pardo added.

Simpson is regarded by many as one of America’s most notorious criminals. He was close with the Kardashian family in the 1990s, right around the time his ex-wife Nicole Brown Simpson and her friend Ron Goldman were murdered. Robert Kardashian was one of the lawyers on his defense “dream team.” Jenner and her ex-husband were very close with Nicole and Simpson, his manager explained.

"They all took their vacations together,” Pardo said. “There was a lot of partying going on back then.” The manager added that Jenner wasn’t known for her fidelity. "Kris cheated on Robert; she was known for having a good time."

Claims that Simpson is Khloe’s father were deemed “100 percent false” by Gossip Cop in January 2012, and Jenner naturally denies it. “I have never heard such crap in my life,” the 58-year-old Kardashian matriarch told “Good Morning America” in a 2012 interview about the incessant reports that her third daughter was not her ex-husband’s. "I was there, right. I gave birth, I know who the dad was. Everything’s good. We’re all good,” she added. “It’s the family joke because Khloe was blond and not dark-haired. People just … get a life.”
