Though tabloids are on the lookout for a baby bump, Kardashian said she hadn't seen any major "physical changes."
"I think until I really start seeing a belly, it won't really sink in," Kardashian said. "It's just like a weird realization, but I think until you start seeing the physical changes, you know, and every day is different."
Guthrie also asked whether Kanye West had told her he planned to reveal the pregnancy news at one of his concerts. "He just says what he feels," Kim responded.
Kim might be looking forward to the possibility of marriage to West, but she still hasn't finalized her divorce with Brooklyn Nets player Kris Humphries.
"I can't really speak for anyone else, it's a process," Kardashian said of Humphries, who has yet to sign the divorce papers.
