'Keeping Up With The Kardashians': Kris Jenner's Huge Lip Gets Family Suspicious (VIDEO)

If that was an allergic reaction, Kris Jenner must have slept in whatever she was allergic to. Or, Kim Kardashian's suggestion that perhaps she snuck out in the middle of the night to get plastic surgery was perhaps more on the money. Either way, that was one huge lip on "Keeping Up with the Kardashians" (Sun., 9 p.m. ET on E!).

The kids were stunned by what they saw on Kris' face, as the vacation in the Dominican Republic was winding down. Kris insisted her massive upper lip was the result of some kind of allergic reaction, but to what was never revealed. Collagen perhaps?

No matter its cause, the lip was certainly the most hilarious moment of the episode, and the most disturbing at the same time. Bruce wasn't very supportive either, saying it was divine retribution for Kris reaching out to contact Todd, her ex. Maybe that's why he was snapping at Scott as well -- after a prank that scared the Jenner girls -- or maybe that's just because Bruce doesn't really like Scott in general right now.

Ultimately, though, Bruce talked to Scott about feeling left out in the family, and in the process he realized he needed to be more supportive in his own marriage. Kourtney even gave Scott a commitment bracelet; which is going to have to do in lieu of marriage right now. So it was like a big Kardashian hug to wrap up their vacation.

"Keeping Up with the Kardashians" heads home, Sundays at 9 p.m. ET on E!
