Kim, 33, is currently on holiday in Punta Mita with husband Kanye and flaunted her curvaceous derriere while relaxing on a sun lounger.
Apparently, according to Kim, she was trying to sleep while the picture was taken, which is why she had turned away and therefore given her bum full exposure. Sure.
Posting the snap on Instagram, Kim explained: "Let me sleep!!!!"
Kim and Kanye are holidaying with friends and last night enjoyed a traditional Mexican dinner of quesadillas washed down with margaritas.
During their evening out, the couple - who married in Italy in May - struck a pose by a swimming pool, just as the setting sun turned the sky pink. Pretty perfect, eh?
US reality star Kim shared the photo with fans online, simply saying: "#MexicoNightsWithMySexyMan."
Kim and rapper Kanye - parents to daughter North - are massive fans of Mexico and have travelled down from their home in Los Angeles several times in the past few months.
Following their wedding, Kimye first holidayed in Ireland before enjoying a second - and slighter warmer - honeymoon in Mexico.
Last month, Kim and Kanye revisited the same plush Mexican resort for a few days break in between work commitments.
We're not jealous...much.
