Khloé Is a Kardashian --Kris Jenner

"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." 

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."
