O.J. Simpson Reportedly Adding Khloe Kardashian to His Will

O.J. Simpson is making headlines again, this time because he believes that Khloe Kardashian is his daughter.

Simpson even plans to add Kardashian to his will, though you have to wonder what money he could possibly have left to leave to anyone.

Last year, Kardashian's mother, Kris Jenner, wrote a memoir about an affair she had while married to Robert Kardashian.

She spilled that the timing of the affair was close to when Khloe was conceived.

Jenner called the man "Ryan," and explained how they had "wild sex everywhere, all the time" in cars, pool houses and on tennis courts.

She further explained, "One minute I was making brownies for my friends and having a family barbecue, the next I was in the middle of an insanely intense affair."

She added, "I would tell Robert I was going out to lunch and I would end up at Ryan's apartment having crazy, fabulous sex for hours in the middle of the day. I would drop Kourtney, Kimberly, and Khloe off at school and rush straight to Ryan."

Mother of the year, right there.

The National Enquirer reports that O.J. believes he's Khloe's father, with a source squealing: "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."

The insider adds, "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.'"
