“Amazing What Money Can Do To A Face”: Jenner Sisters Go Viral For “Drunk Walks” In Bikinis

And for the Kardashian/Jenner family, it seems as if many of their vacation itineraries follow a rough plan, implemented in them by “momager” Kris Jenner .

An insider told Daily Mail that they tend to share a “playful competitiveness” with one another.

“It’s not mean, it’s more inspirational,” they clarified. “They all like to look their very best and they encourage each other. Often they workout together or trade diet secrets. They are supportive. But they really all do want to look amazing — no one wants to be the dumpy one.”
