O.J. Simpson Adding Khloe Kardashian to Will, Claims She is His 'Naural-Born' Daughter

Disgraced former football legend O.J. Simpson is adding Khloe Kardashian to his will, the National Inquirer is reporting. Simpson is also allegedly cutting his eldest daughter Arnelle from his will.

According to a source for the National Inquirer, "O.J. believes Khloe is his natural-born daughter through his affair with Kris Jenner when she was married to his buddy Robert Kardashian-and he wants to do something about it."

"At 65, he's tired and becoming increasingly aware he may not ever leave prison alive. He says he wants to 'do the right thing,'" the tabloid reported.  Simpson is currently serving a 33-year sentence for armed robbery and kidnapping, the International Business Times reported. The former athlete will become eligible for parole in 2017.

Rumors over the true paternity of the youngest Kardashian sister have circulated since details of Kris Jenner's affair while married to the late Robert Kardashian became public. The elder Kardashian was one of Simpson's attorneys during his 1994-95 murder case.

According to the report by the tabloid, Simpson is also planning to cut his oldest daughter from his will after accusing her of recklessly spending his money on "booze, parties, lavish vacations and shopping."

The source told National Inquirer, "At first they thought he was just making a big joke, but when they realized he was serious, they were flabbergasted. They are furious and wonder why they have to share the wealth with a complete stranger."

Another source told the tabloid, "They think he is a real jerk for taking out everything on Arnelle, who uprooted her life in Los Ange­les to move to Florida to take care of him. By cutting Arnelle out of his will, his kids feel O.J. is being cruel. And they think that adding Khloe is just plain revenge. I'm sure if O.J. kicks the bucket and leaves Khloe money in his will, she's not going to turn it down."

Meanwhile, the Jenner-Kardashian matriarch has repeatedly refuted rumors that Simpson is the father of Khloe Kardashian. Confirmation over the will change has not be given by Simpson or his family.
