The wait is almost over.
But Khloé revealed that quite some time actually elapsed before it was known whether Kim was having a boy or a girl.
"It was crazy because we went to three different doctor appointments and the baby kept sitting, like, Indian-style," she said. "So we couldn't tell the sex and it was frustrating, so we were so happy to finally find out."
Unfortunately, Kanye wasn't around when the moment of truth occurred.
"He was at all the previous ones where we couldn't find out the sex of the baby," Khloé said. "So that was just the one he wasn't at. But we were videotaping it on our iPhones and everything...I think he had a concert."
In other words, there's no trouble in paradise.
"They're great," assured Khloé. "He's in L.A. now with Kim and they're great."
