The latest development in the Who's Your Daddy? drama for Khloe Kardashian is a new tabloid report on Wednesday that claims O.J. Simpson is actually her father, but sister Kim stepped in to dispel rumors.

Now we have all the answers! It makes sense now! Khloe u are so tan! Kim Kardashian jokingly wrote on her blog accompanied by The National Enquirer cover, brushing off the false report.

Here's the origin of the rumor.

On Wednesday, The National Enquirer ran a cover story alleging that Simpson, currently serving time in prison, is Khloe Kardashian's father.

O.J. told me Khloe's his child, an unnamed source told The National Enquirer.

According to the tabloid, Kardashian's mother, Kris Jenner, had several affairs with Simpson in 1983, coincidentally when Kardashian was conceived.

Robert Kardashian, the late husband of Jenner and father to the girls, was a friend of Simpson's many years before Simpson faced charges for the double murder of his wife Nicole Brown and Ron Goldman in 1995. According to the source, Jenner was close to both Simpson and Brown.

O.J and Kris have known each other for more than 30 years, the source said. But they fell out when Nicole was murdered.

Many years before the incident in 1995, the source said that Jenner was one of the many trysts he had over the years, which was a big secret for the two families.

O.J. bragged about his sex life and many female conquests, which he said included some of his best friends' wives, the source said.

Ironically enough, the source claims Jenner was not only one of the conquests, but also the mother of a secret love child Simpson allegedly had.

He used to tell us way back - even before he and Nicole got divorced - that he had a love child with the wife of a wealthy family, the source said referring to Khloe Kardashian.

However, Simpson never spread news of the love child as the news could have threatened high-profile endorsements deals adding up to $10 million he was engaged in and the relationship with his own children.

He always worried that his children would find out some day and become very angry with him, the source said.

And if the testimony of an unnamed source wasn't enough proof, the tabloid goes a step further to compare the like features of Kardashian and Simpson's 26-year-old daughter Sydney.

The latest rumor comes after reports emerged from Jan Ashley and Ellen Kardashian, the ex-wives of the late Robert Kardashian, that he was not the father of Khloe.

Khloe brought it up all the time, Ellen Kardashian, the third wife, said. She was tall, had a different shape, light hair, curly hair. Didn't look anything like the other three children.

Kris Jenner appeared on Good Morning America last Thursday to quell the gossip.

I have never heard such crap in my life, Jenner said. I mean, I was there. I gave birth. I know who the dad was.

And according to Kim Kardashian, this latest rumor involving O.J. Simpson is just as false as the others.

Simpson has been imprisoned in Nevada since 2008 on a 33-year sentence for kidnapping and armed robbery.

Khloe Kardashian has not officially responded to the Simpson-father rumor, but posted on Twitter on Wednesday, It only makes me stronger!
