Rihanna: Nude Photo Drama

Rihanna's camp is firing off the first response to nude pictures, allegedly of Rihanna, that hit the internet today.

RihannaTMZ has learned the legal department at Island Def Jam Music Group, RiRi's label, sent a letter to at least one website that published the photos. The letter refers to "unauthorized photos purported to be...Rihanna," demands that the photos be removed from the site, and calls the photos a violation of "the Artist's rights."

It's not clear whether Rihanna really is the woman in the buff because you can't see her face in the nude shots. She is clearly pictured in two fully clothed pics.

Interestingly, the letter from Island Def Jam does not deny (or confirm) if it's really Rihanna.
