Kim Kardashian Mocks National Enquirer's Claim O.J. Simpson Is Khloe's Biological Father

At least the Kardashians have a sense of humor about all the wild accusations made in recent weeks.

Kim Kardashian mocked the tabloid the National Enquirer on Twitter yesterday, posting a photo of the magazine's current issue, which claims her sister Khloe Kardashian's biological father is O.J. Simpson. Kim wrote, "Now we have all the answers! It makes sense now! Khloe u are so tan!"

The family has long joked that Khloe is adopted because of her lighter hair and towering physique, but allegations that Robert Kardashian did not father Khloe surfaced last week.

The family was quick to dismiss the claims but seemed very hurt by the accusations from Robert's second wife and his widow.

Khloe responded on Twitter, writing, "The audacity you have to mention my father's name like this! Should be ashamed of urself," while her mom Kris Jenner appeared on "Good Morning America" telling Robert's second wife Jan Ashley and widow Ellen Kardashian, to "get a life."

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

The National Enquirer's claim is certainly laughable at best. It's well known that O.J. Simpson was good friends with Robert Kardashian and his then wife Kris Jenner. However, it's also well known that Jenner was furious with Robert over his decision to defend Simpson in his trial for the murder of his wife and Kris' best friend Nicole Brown Simpson.

Kim seems to be handling the drama with humor, but Khloe may not be taking it so well. The 27-year-old reality star has also been busy shooting down rumors that she and husband Lamar Odom are undergoing fertility treatment and It seems the drama is getting to her.
