Kendall Jenner Shuts Down Pregnancy Rumors with Bagel Explanation

Kendall Jenner is NOT the 4th Kardashian who's expecting a bundle of joy -- she's just got a bun in the oven ... otherwise known as a bagel.

Kendall posted a mirror selfie Saturday and almost immediately had to respond to rumors that she was pregnant. Her slim figure looked a bit more hourglass-like in the pic, and people sorta lost their s***.

As it turns out, Kendall isn't preggo -- she's just fan of the doughy goodness that are bagels.
