I would not take anything that happens in the storylines of the Kardashian shows to be verification of what they've done in real life. Ever since the episode years ago where Kris was supposedly putting viagra in Bruce's coffee, and Rob accidentally drank it, I've been convinced that the cameras do NOT capture their real lives. They come up with storylines they want to present, and use them to push their publicity machine. So when Kim got pregnant (or Kourtney before her) they come up with a storyline for the show to tell the story they want to present, and start the cameras rolling. I think they incorporate some aspects of real life that they choose to share. But I wuold not ever say "Khloe said this on the show, therefore it is real".
