Kim Kardashian plan baby No. 4

Kim Kardashian and Kanye West are reportedly planning on having a fourth baby sometime soon, ET Online has revealed.

The pair already share three kids together -- North, 5, Saint, 2, and Chicago, 7 months -- but a source close to the couple tells ET that if a fourth child "is in their cards," they would be "ecstatic" with the new addition.

"Kim and Kanye have always wanted a big family," the source says. "Kim loved growing up with a lot of siblings and wants the same for her children."

“I don’t know. I don’t know. I read something that it was, you know — none of that was true,” Kardashian West, 37, said during an interview with E! Newsthat aired Wednesday after being asked if she and her husband Kanye West are planning for a fourth child.

“But I’ve been really open about it and talked about it on our show, so I don’t know,” Kardashian West also told the outlet.

“We start filming season 16 next week, so if I think about it more and it’s gonna happen, you’ll definitely see it on the show,” she continued. “But as of now, no.”
