On Monday night Kim Kardashian posted the photo of herself and hubby Kanye West above and wrote, "#MexicoNightsWithMySexyMan," and it looks like the couple are having a blast at pal Joe Francis' pad south of the border.

Judging from the smiles on their faces, it seems like they're still on their honeymoon -- which is amazing when you think about the fact that Kim's third marriage has now lasted several weeks longer than her 72-day union to NBA star Kris Humphries. Nice work, you two!

Of course, Kim had to throw in a pic of her big ol' booty for good measure, and the reality starlet also posted a pic of herself on the water with a gal pal and added, "Not easy taking a selfie jet skiing." Hmm, maybe she should stick to the shots of her rear. I mean, aside from Nori's precious face, that's really the only thing Kim posts these days that's remotely interesting...
