Rihanna celebrates her new boots with another naked Instagram. 

Oh joy! Another naked Rihanna photo! Again. For a moment there we'd almost forgotten what the "Stay" singer's naked butt looked like. Because she HAS actually been wearing clothes recently, what with her new collection of, well, CLOTHING for River Island. That said, it's a great day for fans who support Rihanna's aversion to clothes, and who also long to see more naked Rihanna in just an Indian headdress, naked Rihanna with Kate Moss on the cover of V magazine, and naked Rihanna in GQ Magazine. Well, now Rihanna's bum is back!

Last night, Rihanna Instagrammed a photo of herself rocking a brand-new pair of custom Prada boots sent to her by, ahem, Miuccia Prada herself. She captioned: "Gotcha b---h tip toeing on my marble flo'!!! Sick ass custom Prada boots! Miuccia you RULE!!! Thank you."

You know what? If we know Rih (and we like to think that we do), she was probably ALREADY hanging out naked when the shoes arrived and was way too exhausted (gee, wonder why?) to put on ANY clothes whatsoever. (Well, save for a thong, but would you really call a thong an article of clothing?) Next time, Prada, you should probably send Rihanna some CLOTHES TO WEAR WITH THE BOOTS. And you can send me clothes some too, while you're at it.
