While Kim is busy being fat shamed over those unflattering bikini pics from Mexico, her little sis is busy taking the crown!

Khloe Kardashian hit the studio in LA today in a sheer bodysuit, bra, and jeans, and we seriously can't believe our eyes! She has the flattest abs we've ever seen! Her transformation from the "fat" sister, which we never thought she was by the way, to the hottest of the K clan is now complete.

Love ( and daily workouts!) does a body good, and it sounds like the Good American designer is head over heels and ready to take a walk down the aisle.

"They’ll almost certainly get engaged before the end of summer," a source dished to Us Weekly about the reality star's relationship with boyfriend Tristan Thompson.

She might want to strip down and do some sexy photoshoots while she still looks this bangin', because the 32-year-old might have a bun in the oven sooner rather than later. "[Khloe] definitely wants a big family. She wants multiple kids!" the source added.

There will be no need for shedding before the wedding if her beau pops the question, that's for sure!
