Kris Jenner's plump pout isn't the result of injectables.

On Sunday's episode of Keeping Up With the Kardashians, the momager, 56, suffered an allergic reaction that caused her upper lip to swell during a family vacation in the Dominican Republic. "I'm a mess," she complained, pointing to her swollen, puffy mouth. "My lip looks like a Who from Whoville."

Kris didn't receive much sympathy from her children Kim Kardashian, 31, and Rob Kardashian, 25, who pointed and laughed at her misfortune. Kris' husband, Bruce Jenner, 62, wasn't too supportive, either. "God is punishing her for giving Todd her email," he huffed, alluding to her recent exchange with an ex-lover.

In a voiceover, Kris -- who got a facelift before her daughter Kim's wedding to Kris Humphries in August 2011 -- revealed her husband's snide comment hurt her feelings. "Bruce is usually the one to give me support in any situation. At a time like this when I'm feeling really vulnerable and kind of scared and he's going to be mad at me?"

Keeping Up With the Kardashians airs Sundays at 10 p.m. EST on the E! network.
