Khloe Kardashian Odom is, understandably, not very pleased with two of her father’s former wives.

Jan Ashley and Ellen Kardashian, the women Khloe’s dad married after Kris Jenner, are quoted in Star magazine (via Radar) that the E! reality star is not the biological child of the late Robert Kardashian.

Not surprisingly, Khloe lashed out at such a claim via Twitter.

“The audacity you have to mention my father’s name like this!” she tweeted Wednesday morning. “Should be ashamed of urself! I let a lot of things slide but this one is really low … YOU ARE DISGUSTING! (yes you know who YOU are).”

According to Star, Jan alleges that Robert told her that Khloe was “not his kid” shortly after they tied the knot. Ellen, too, claims that Robert supposedly questioned whether he was actually Khloe’s father prior to his death in 2003.

“She looked nothing like the rest,” Ellen told Star. “She was tall, had a different shape, light hair, curly hair. Didn’t look anything like the other three children.”

While such differences certainly don’t prove anything, Khloe herself did playfully bring them up during a hilarious 2009 episode of “Keeping Up With the Kardashians.” In a the clip from the show, Khloe convinced herself she was adopted and obtained her mom’s DNA to find out if Kris is in fact her mom. (The test results proved she was, FYI.)

Meanwhile, there’s been no response yet to Star’s story from Khloe’s sisters Kim and Kourtney or their mom.
