The Kardashian-Jenners In Their Calvins

Her family tries to tell her she looks great, but Jenner isn't hearing it.

All the compliments in the world couldn't calm Kylie Jenner's anxiety as she prepared to do her first half-naked photoshoot since the birth of her daughter Stormi.

In a sneak peek at Sunday's new episode of "Keeping Up with the Kardashians," Jenner expresses unease with her body before doing an underwear shoot with all of her sisters for Calvin Klein.

While Khloe Kardashian tells her she looks "amazing," Jenner replies by glumly saying she's "still 158" pounds.

"And your belly button is back to normal," a still-pregnant Khloe says. "I'm 198 right now, so if you want to f--king play this game. Your belly button went back to normal."

But Jenner doesn't agree, saying "it looks different" and disagreeing again when Khloe says her body "looks f--king crazy."

"This is gonna be kind of my first photo shoot after Stormi and doing like my first few fittings and getting back into it, it's kinda of hard and discouraging," Jenner admits in a confessional before they all step out on set.

Of course, we already know how those photos turned out -- see them all below. "Keeping Up with the Kardashians" airs Sunday on E!
