TF? Rihanna bares her bare breasts in see-through top (see photos)

Rihanna but why? The singer bared her bare boobs in a sheer black top with nothing on underneath as she attended Balmain's Paris Fashion Week after-show party yesterday night. See the pics after the cut...but if you're viewing from the office, biko ji wa yo...(sofry sofry). It's quite x-rated..:-)
