Kourtney Kardashian poses nude for GQ Mexico in sexy new cover shoot

Hot mama!

Kourtney Kardashian is GQ Mexico's cover star for its December/January issue, and the mother of three has never looked better than in the accompanying cover shoot, which she helped to unveil on Instagram on Monday.

The issue features two covers: One shows Kourtney wearing a simple white leotard as she sits on a chair, while the other shows her slouching in a pair of unbuttoned blue jeans and a blush Calvin Klein bra. It's the rest of the photo shoot, shot by Michael Schwartz, that leaves little to the imagination, though.

The "Keeping Up With the Kardashians" star poses completely nude in two shots, one of which is reminiscent of her famous nude photo shoot from her family vacation to Costa Rica from a few years back. The oldest of the Kardashian sisters dons a variety of lingerie for the rest of the photos, which put her impressively fit physique on firm display.

The headline for the cover story translates to "Kourtney Kardashian to close the year as it should be," which speaks for itself.

Fans of the reality star will recall that her younger sister, Kim, called her "the least interesting [sister] to look at" on a recent episode of "KUWTK." Something tells us she's eating her words.
