Vile: Khloe Kardashian took to Twitter to deny the shocking allegations made by Robert Kardashian's ex-wives, who claim he told them that Khlow was not his daughter
Khloe Kardashian isn't one to keep quiet and today she branded her husband's ex-wives 'disgusting'. She took to Twitter to deny the shocking allegations made by Robert Kardashian's ex-wives, who claim he told them that Khloe was not his daughter. The 27-year-old reality TV star posted: '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).'
The posts were clearly directed at Jan Ashley and Ellen Pierson who have both spoken out to say that Robert told them Khloe was not his.
Ms 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.'
And Ellen Pierson, 63, who married Robert 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.
Claims: Two of Robert Kardashian's ex-wives have come forward claiming the lawyer told them Khloe Kardashian, left, was not his real daughter, like older sisters Kim and Kourtney
The reality star has hit back at the claims, calling them 'really low'.
A spokesperson for Khloe told MailOnline today: 'The story is NOT true. It’s ridiculous.'
But while Khloe has slammed the allegation she has herself questioned if she was adopted on the family's reality TV show.
Viewers of Keeping Up With The Kardashians did see her question who her parents were in an episode in 2009.
The reality star wanted to prove she was not adopted and tested the maternity of her mother Kris Jenner.

While she proved she was Kris's daughter she did not compare her DNA with her siblings to prove conclusively that Robert is her biological father.
In an explosive interview with Star magazine, Ashley 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.'
Proof: Khloe made Kris take a DNA test to prove she was her child but she did not confirm paternity
She claims Khloe, who is married to Dallas Mavericks basketballer 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.'
Different: Khloe has often pointed out that she looks nothing like her older sisters and their mother Kris, far right, said once people asked whether she was 'the milkman's child'
She said Robert, 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,' Ellen said.
'Any normal man would if they knew their wife had cheated on him.'
Khloe has responded to the claims today on Twitter.
