Kylie Jenner is hell-bent on showing off her bodily assets at Coachella -- and she showed them to the world in these sexy Instagrams, straight from the desert!

In the first, Kylie dons a pink wig with a cap and what appears to be Kayne West's design for Adidas -- and is basically nude-colored granny pants. Sexy? We guess so ... but her second selfie/belfie, is a teensy bit hotter. The youngest Jenner exposed her generous rump in a black bikini at the pool. Seems this girl wakes up early to get her Instagram work done before she heads out to the festival. Oh yeah! Coachella! She almost forgot what she's there!
