WOW! Is all I said when I saw these pictures! Seeing a Kardashian naked isn't anything new...but Kourtney has always been my favorite sister. I know J Lo breaks the internet with her thong & bikini pictures at 50 but Kourtney is not too shabby at 39 in this naked GQ Mexico magazine photo shoot! Hope you have fun looking at these pictures like I did....click here to see the photo shoot.
