Robert Kardashian isn't the biological father of Khloe Kardashian, according to Radar Online.
Jerry Oppenheimer, a close friend of the late Robert Kardashian, made explosive claims in his tell-all book The Kardashians: An American Drama.
'When Khloe got old enough, people in the Kardashians’ circle began to notice just how different she really did look and raised questions. Kris would explain away the suspicions by saying that Khloe looked like her maternal great-grandmother, Lou Ethel Fairbanks. And Robert’s friend Joni Migdal recalled how Robert would shrug off their suspicions and claim that Khloe looked just like his mother, Helen, who was Armenian but didn’t have Armenian features', he writes.
Kenn Gulliksen, a different friend of Robert's, claims that the late lawyer admitted to him that Khloe wasn't his biological daughter, but that he didn't want any DNA tests done.
'He didn’t want to find out anything. He told [her], ‘I love Khloe. She’s wonderful. She’s mine, period.’ But he knew that she wasn’t his. His confirmation to me was, ‘she’s mine and I don’t care who the father is,' Gulliksen revealed.
However, in a sworn declaration before his death, Robert swore under oath he had 'four biological children'.
Khloe has questioned the identity of her biological father in the past and nearly had a paternity test on a previous episode of Keeping Up With The Kardashians before changing her mind.
