Let's be honest: We've all thought it. Khloe Kardashian doesn't look like her sisters Kim Kardashian and Kourtney Kardashian, she doesn't act like them and she has little tolerance for the family's shenanigans. Is it possible that she is not really a Kardashian?
Her father is supposed to be Robert Kardashian -- Kim and Kourtney's dad -- but two of the famous late attorney's wives say even he didn't believe she was his.
Jan Ashley, who was married to Robert after he divorced the now Kris Jenner, told Star magazine he was very matter of fact about the situation.
"Khloe is not his kid -- he told me that after we got married," she said. "He just kind of looked at me and said [it] like it was a matter of fact. He said, 'Well, you know that Khloe's not really a Kardashian, don't you?' And I said…'OK,' and that was it."
Ellen Kardashian, Robert's wife at the time of his death in 2003, confirmed to the mag that he told her the same thing -- and said the situation was made even more obvious by the fact that Kris Jenner admitted cheating on him.
"Robert did question the fact that Khloe was his," Ellen said. "Any normal man would if they knew their wife had cheated on him."
Even Khloe seemed to know something was up, Ellen said. "Khloe brought it up all the time," she told Star. "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."
Regardless, Khloe and Robert were very close, and Khloe seemed the most affected by his death, even getting a DUI on the anniversary of his passing because she was so bereft.
"He never would have considered a DNA test," Ellen said. "He loved her very much."
However, Khloe is fighting back against the allegations -- and she is totally pissed.
"The audacity you have to mention my father's name like this! Should be ashamed of urself!" Khloe wrote on Twitter. "I let a lot of things slide but this one is really low… YOU ARE DISGUSTING! (yes you know who YOU are)"
Wonder which wife she's talking about?
