Two of Robert Kardashian’s ex-wives claim Khloe does not have the same father as her older sisters Kim and Kourtney.
The late businessman’s ex-wives have come forward saying he expressed doubts over the paternity of Khloe Kardashian.
Khloe Kardashian has hit back at the claims, calling them “really low”.
In an explosive interview with Star magazine, Jan Ashley, who married the businessman after Khloe’s mother Kris Jenner, said: “Khloe is not his kid – he told me that after we got married.”
She added: “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 Pierson, 63, who married Robert Kardashian in 2003, just two months before his death, has also come forward after eight years of silence to “tell the truth” about the Kardashian family.
Ellen Pierson claims Khloe Kardashian, who is married to Dallas Mavericks basketball player Lamar Odom, knew she had a different father to her sisters and younger brother Rob.
“Khloe brought it up all the time. 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,” she said.
Ellen Pierson said Robert Kardashian, who is of Armenian descent, had told her that he and Kris were not sleeping together at the time Khloe was conceived.
“[But] he never would have considered a DNA test. He loved her very much. Robert did question the fact that Khloe was his,” she said.
“Any normal man would if they knew their wife had cheated on him.”
Khloe Kardashian has responded to the claims today on Twitter.
She wrote: “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… YOU ARE DISGUSTING! (yes you know who YOU are).”
Khloe’s mother, Kris Jenner, 56, recently admitted in her new book that she cheated on Robert during their marriage and Jan and Ellen her husband also knew.
Since Robert Kardashian’s death, Ellen Pierson had experienced financial difficulties, filing for Chapter 7 bankruptcy in 2010.
The home Ellen and Robert Kardashian shared in Indian Wells, California, was sold after going into foreclosure in October.
Kris remarried Olympian Bruce Jenner in 1991 and the couple had two daughters, Kendall and Kylie.
Bruce Jenner already had four children from two previous marriages: Burt, Casey, Brody, and Brandon.
Khloe Kardashian is often talking about how she looks nothing like her sisters, and Kris Jenner has been quoted as saying people asked her whether she was “the milkman’s daughter” when she was born.
On Khloe Kardashian’s blog in June 2010, she shared a number of pictures of her and the attorney.
She wrote: “Father’s Day is two days away, so in preparation I wanted to post this photo album (mostly old school pics) dedicated to my dad and to Bruce.
“I was seriously the luckiest girl in the world growing up because I had two amazing dads who not only loved us kids more than anything, but adored each other as well.
“My dad and Bruce were always really close – Kendall and Kylie even called my dad Uncle Robert which I loved.
“Father’s Day is always a bittersweet holiday for me because I of course miss my dad, but it also reminds me of how truly blessed I am to have had two incredible fathers.”
