Khloe Kardashian could be O.J Simpson's daughter.

The manager of the disgraced former football player, Norman Pardo, has reignited speculation that O.J could be the reality star's biological father by suggesting he shared a "close" relationship with Kris Jenner throughout her marriage to late ex-husband Robert Kardashian. "It's all going to come out sooner or later. Khloe could be O.J.'s kid," he told In Touch Weekly.

It's suggested Kris - who admitted to an affair during her first marriage - struck up a "close" bond with O.J. long before Robert, successfully defended the star in the 1995 trial into the murder of his ex-wife Nicole Brown - adding that the couple even used to join the Kardashian's on holiday prior to her death.

"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," Norman continued.

Both Kris and Khloe have refuted claims that she was not biologically fathered by Robert. Kris admitted to having an affair with a man under the pseudonym of "Ryan" in her memoir last year, and while Hollywood manager Todd Waterman stepped forward to reveal his identity, she has denied rumors of an affair with O.J.
