Those pesky rumors that O.J. Simpson is Khloe Kardashian's father won't go away.

Now O.J.'s manager, Norman Pardo, is reportedly claiming the disgraced football star could be her dad. Pardo tells In Touch Weekly, "It's all going to come out sooner or later. Khloe could be O.J.'s kid."

O.J. used to be good friends with Kris Jenner and her then-husband Robert Kardashian, who was also part of the Dream Team in his 1995 murder trial. Pardo explains, "They all took their vacations together. There was a lot of partying going on back then. Kris cheated on Robert — she was known for having a good time."

Pardo claims that if O.J. — who is serving a 33-year sentence for kidnapping and robbery in a Nevada prison — is freed, he plans to reveal more details about his relationship with the reality star family. The manager adds that whenever he brings up whether he conceived a baby with Kris, he "giggles."

Kris Jenner denies the claim.
