Kim Kardashian West in a Bikini Bouncing on a Trampoline ... That's All, Really

Kim Kardashian West did a shameless promo ... for gravity and, if you weren't before ... you're about to be a big fan of it.

Look, we're not trying to score a Pulitzer here. It's Kim. It's a white bikini -- a small bikini -- a trampoline, and umm ... that's it, really.

Although we definitely do NOT want to undersell the miraculous work put in here by Kim's bikini. The fabric is holding everything in place.
