We’re pretty well-versed with the whole concept of where babies come from (spare us, mom!) — but that doesn’t mean Kim Kardashian’s pregnancy is making, like, any sense to us…

It seems like only days ago that she was barely showing. But today, her baby bump is HUUUGE — and, naturally, the 34-year-old threw on a super-tight dress and took a selfie to show it off!

Good night baby

Kim, who’s expecting a baby boy due December, is well aware that she was barely showing earlier in pregnancy.

A few weeks back, Mrs. Kanye West tweeted, “I secretly loved the rumors I was faking my pregnancy [because] I was so skinny! LOL Well can’t hide it now! 5 months (20 weeks) and 20 lbs. up.”

LOL!

Well, we think you’ve been glowing all along, Kim!
