Kourtney Kardashian has a human being growing inside of her.

This results in a few bodily changes. For example, the knocked up socialite told People:

"My boobs got huge right away. They got so sore, that if anyone even brushed up near me, I would scream."

That's what you get for watching your sister's instructional video too many times.

Kourtney also said she's not afraid to pack on the pounds, adding that she's already gained 10 pounds.

"I'm really embracing it. I feel like it's such a beautiful thing, that every woman who goes though it, should embrace it. I think if you're naturally skinny, and pregnant, and that's how your body is, that's fine."

In conclusion, Kim's sister wants to "do what's healthy for the baby." Who said she wouldn't be a great mother?!?
