Rihanna's Under-Boob Tattoo Paints A Mustache On The Mona Lisa (Picture)

(WARNING: The image way below is not exactly completely safe for work. There's a little something showing off to the left that Rihanna might have meant to cover up.)

Rihanna, what in every single known Blue Hell did you do?!

Perez Hilton broke the news Monday that the Grammy- and MTV Video Music Award-winning singer and "Battleship" co-star apparently felt that that her upper torso just wasn't pleasing enough to the eyes. The solution? Permanent ink.

Rihanna tweeted the risque photo identifying the ink across the underside of her breasts as Isis, the Egyptian goddess of magic and an ally to sinners. Thankfully, she did also remarked that neither the image nor the placement are without significance to her - or, for that matter, for those ladies who follow in the singer-actress' footsteps.

OK, first and foremost - FRACKING OUCH! Right across the ribs like that? And with that kind of detail? Let's all admit, that alone takes some brass ones, as it's understood that the ribs and right onto the spine are reputedly two of the most painful places to put a tattoo.

But more importantly, why do that to such a naturally beautiful part of a woman's body? Granted, tattoos can be the most individual, personal, meaningful means of personal expression. That being said, there are parts of the human body that are just better left unspoiled.

Especially with a set of breasts as beautiful as Rihanna's.

Hey, nipple piercings at least come out.

Just....damn.
