Kim Kardashian's latest selfie is all about the butt.
The reality TV star posted a new Instagram photo from her latest trip to Mexico -- once again putting her famous curves on display in a teeny bikini that can barely contain all that booty.
"Let me sleep!!!!" she captioned the pic, which shows her reclining on a day bed.
This is hardly the first photo Kim has shared of her derriere in a bikini ... she's been on a rear end kick lately -- just look at some of the other selfies in the gallery above!
The revealing pic comes after Kim opened up about her post-baby bod and how she still wants to drop another 15-20 pounds.
"Just need to get down to my weight a few years ago. Not gonna complain anymore. Starting diet TODAY! No carbs. crazy workouts. Whos with me?" she posted earlier this month on Twitter. "ughhhh my hips & butt are huge now! they were big to begin with!"
Despite some concerns about her physique, Kim clearly has no problem showing it off, does she?
