Of all the crazy rumors surrounding the Kardashians, one of the craziest of all just will not go away, and has come back with a vengeance yet again:

Alex Roldan, long rumored to be Khloe Kardashian's biological father, is the subject of tabloid speculation once more this month, with a big twist:

According to insiders, Khloe reportedly confessed to her estranged husband Lamar Odom that Robert Kardashian Sr. was NOT her real father!

"Khloe told Lamar that she knew that she didn’t have the same dad as her sisters,” says a source of the couple, who are still not divorced.

Tabloids have also hinted that Robert Kardashian Jr., a.k.a. Rob Kardashian, plans to OUT Khloe's secret in a tell-all interview as payback.

Payback for Khloe saying Rob partied with whores at her house on a recent episode of E!'s Keeping Up with the Kardashians, that is.

Speaking of the family franchise, an Australian gossip magazine says Khloe will "face her father" on the Season 10 finale later this year.

Some of the stuff writers make up is just hilarious.

Almost as much so as reports that the biological father of the youngest of the three Kardashian sisters is not Rob Sr. OR Alex but ... O.J.

Thomas Scotto, O.J. Simpson’s friend, has spoken on the topic before and said that he believes the Juice could, in fact, be Khloe's dad.

He said, “O.J. shared [this] with me on a few occasions ... to put this rumor to rest, I suggest that O.J. and Khloe submit to a simple DNA test."

"That would end all speculation and rumors."

"The truth can be revealed once and for all. Simple, if she wants everyone to know that he is not the father, otherwise she wants to hide the results.”

The only truth we can attest to for certain here is that this has been one seriously entertaining article and enjoyable read from start to finish.

Well played, fake sources!
