khloe kourtney kim kardashian getty Khloe Kardashian irate about rumor that she's not a real KardashianKhloe Kardashian is tweeting up an indignant storm after Star magazine ran a story suggesting that she may not actually be the daughter of Robert Kardashian.

“The audacity you have to mention my father’s name like this! Should be ashamed of urself! I let a lot of things slide but this one is really low,” she writes.

In Star, two women who were married to Robert Kardashian after his 1990 divorce from Kris Jenner say that the lawyer questioned whether or not he was really Khloe’s father.

“Khloe is not his kid. He told me that after we got married,” ex-wife Jan Ashley, the first spouse after Kris Jenner, tells Star.

“Khloe brought it up all the time,” Ellen Kardashian, 63, the woman who was married to Robert Kardashian at the time of his death, says. “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.”

“Robert did question the fact that Khloe was his,” Ellen Kardashian continues. “Any normal man would if they knew their wife had cheated on him.”

In a recent memoir, Jenner admitted that she had affairs while married to Kardashian.

“YOU ARE DISGUSTING! (yes you know who YOU are),” the 27-year-old tweeted in response to the story.
