The reality star is pregnant with her second child but hasn't been sporting that much of a baby bump in recent pictures.
She reckons that's about to change, though!
Kim, 34, tweeted yesterday: "I'm at the stage where I wake up with a flat belly but then as I eat and by the end of the day it pops out! This means it's about to pop!"
The Keeping Up With The Kardashians star is keeping up with her workouts while pregnant.
Yesterday, she walked three miles and did 100 squats. Impressive!
