"The baby is coming," Kim tells Hollyscoop. "All this stuff is going to take so much time, and it's going to be exciting at the same time."
Kim, who recently went shopping for baby clothes with her older sister, says Kourtney has that proverbial glow. "She's a really cute pregnant girl. It's just a big belly," she says.
But so far Kourtney has none of the junk-food cravings. "She really just wants to eat healthy food," Kim says. "She just only craves healthy food ... I gotta get pregnant."
