In this week’s National Enquirer cover story, O.J. Simpson is apparently claiming he’s Khloe Kardshian’s real father. 

It’s an interesting idea.  O.J. was best friends with Robert Kardashian . . . and he was part of the legal team that helped get O.J. acquitted of murder charges.

(We told you last week that two of Khloe’s step-moms have come forward saying Robert didn’t believe that Khloe was his child.)

And Khloe’s mom, Kris Jenner, was BFFs with O.J.’s wife Nicole Brown.

As ridiculous as this concept is . . . or perhaps because of how ridiculous it is . . . Kim Kardashian was able to laugh it off on Twitter.  She said, “Now we have all the answers!  It makes sense now.  Khloe u are so tan!”

Khloe herself Tweeted, “It only makes me stronger!”

But it’s not clear if she was referring to the O.J. story or the rampant rumors that she’s undergoing fertility treatments to get pregnant.
