Khloé: Not a Kardashian?
On Wednesday, Khloé Kardashian called reports
that she was not the biological daughter of the late Robert Kardashian "really low" and "disgusting." On Thursday, Khloé's mom and Robert's ex-wife, Kris Jenner, also spoke out about the claims.
"I was there, I gave birth," Jenner, 56, told ABC News
, following allegations made by Robert's other ex-wives, Ellen Kardashian and Jan Ashley. "I know who the dad was, everything's good. We're all good. Don't worry about it. Get a life."
In one episode of Keeping Up with the Kardashians
, Khloé, 27, kidded that she could be adopted, but Jenner calls it "the family joke because Khloé was blonde and not dark-haired," like the rest of her brood.
Additionally, court documents point out that when Robert filed to annul his marriage from Ashley in 1999, his declaration to the judge addressed that they did not agree when it came to expanding the family. As he explained: "Since I already had four biological children [Khloé, Kim, Kourtney and Robert], I did not wish to have any more."
