Khloe Kardashian had once questioned whether or not she was a real Kardashian, as played out on the family’s reality show “Keeping Up With The Kardashians.”

But this week, adding flame to the fire, two of the late Robert Kardashian’s ex-wives made some shocking claims about Khloe.

Jan Ashley, 63, who married Robert after Kris Jenner, revealed that Robert told her “Khloe is not his kid– he told me that after we got married,” she told Star.”

Ellen Kardashian, also 63, who married Robert after Ashley told Star “Khloe brought it up all the time,” and “She looked nothing like the rest. She was tall, had a different shape, light hair, curly hair. Didn’t look anything like the other three children.”

Khloe took to Twitter sharing her outrage for the new story.

“This one is really low… YOU ARE DISGUSTING! (yes you know who YOU are),” tweeted Khloe.

While Ashley and Kardashian had their marriage annulled only five months after tying the knot, according to E! who produces the Kardashian reality shows, Robert Kardashian stated under oath that he had “four biological children.”

“I decided that since I already had four biological children, I did not wish to have any more,” he noted while acknowledging he had broken the terms of the agreement he and Ashley had when they married.

Additionally, Ellen revealed even more shocking information about the famous reality family. She reportedly told the magazine that Kris Jenner’s husband, Bruce Jenner, is a crossdresser and that Robert Jenner’s ex-wife are the ones who told her.
