Rihanna Nipplegate 2013: Pop Singer Shows Off Nipple Ring in Black Mini Dress (NSFW)

Thin cotton or wool will do it to you, and Rihanna found out the hard way. (No pun intended.)

The Unapologetic singer was pictured walking into Eden night club in Hollywood on Thursday night. To the naked eye, RiRi's outfit would have been regarded as a simple, yet sexy black mini-cocktail dress, however when picked up by flashing cameras the dress revealed a little more than intended. RiRi's dress turned to sheer when bulbs flashed around the pop star. The singer's dress became see-thru showing off her pierced nipple and thong. Not that it's that big of an issue, considering Rihanna frequently updates her social feed with half-naked pictures of herself and doesn't shy away from other exposing outfits.
