Nobody ever accused Khloe Kardashian of not keepin' it real!
In the clip, Kim goes through her whole ordeal getting pregnant, while dropping the news on Khloe that things finally worked out for her, and she's carrying a baby!
"I really thrived when you were fat and pregnant and they compared you to a whale. That was the first time I was ever the thin one. That's so sad that you guys have to be pregnant for me to be the thin one."
It was all spoken in good nature, of course — LOLz!!
Kim pointed out that Khloe should probably take advantage of the time in the spotlight now that she'll be "the thin one":
"This is your moment to shine. You've got to do every sexy photo shoot you can imagine."
