Our quest to determine whether these breasts really belong to Rihanna continues: and we've just gotten the biggest boon of all (save for actual topless pictures). Observe: Rihanna in a seethrough wifebeater.
From this we can see not only the size and shape of her boobs, but also confirm that, yes, she does indeed have pierced nipples. Very, very interesting...
