Kim Kardashian West is on baby number three. But we’re not spotting any belly bumps soon. Obviously. Have you seen the pics of her lately? Clearly she’s not preggo. But, she actually is. Well, she isn’t. That’s because she’s having her third child via a surrogate. If you’re wondering whether Kim K is having a new little West boy or girl, the reality star and media mogul recently spilled (somewhat accidentally) the sex of her baby while on “Ellen.”

Tomorrow, @KimKardashian accidentally reveals the gender of her new baby. Oh, boy! Or oh girl?

A post shared by Ellen (@theellenshow) on

After a not-so-great second pregnancy, Kim and Kanye went with a surrogate for their next go around. Kardashian West suffered from placenta accreta, a potentially dangerous condition in which the placenta actually grows into the uterine wall. This prevents it from detaching during birth, causing problems for the affected mama.

After going through the pain, stress and scariness of the whole planta accreta situation, Kim didn’t want a repeat performance. When Ellen DeGeneres asked Kim about the baby and her other kiddos (during an interview on her TV show), Kardashian West slipped up when talking about daughter North’s reaction, saying, “And she said, ‘Mom, since baby sister’s not here, I think I need all of her toys in my room and I’ll play with them and just make sure they’re all OK for baby sister’.”

Umm, oops. So there it is. After plenty of media reports suggesting that Kim’s having a girl, we finally have a real answer.
