Khloe is a Kardashian after all. âI was there, I gave birth," Kris Jenner, 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." Legal documents have also surfaced in which the late Robert Kardashian declared youngest daughter Khloe was his biological daughter.
