Khole Kardashian says that the sex of Kim Kardashian and Kanye West‘s baby will be revealed in Sunday’s episode of “Keeping Up With The Kardashians.”

“It was crazy because we went to three different doctor appointments and the baby kept sitting, like, Indian-style,” she told Kathy Lee Gifford on the “Today” show. “So we couldn’t tell the sex and it was frustrating, so we were so happy to finally find out.”

Kanye, she says, was not around when they learned the big news.

“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.”

Furthermore, Khloe says the two are as happy as ever.

“They’re great,” Khloé said. “He’s in L.A. now with Kim and they’re great.”
