Actress Eva Mendes, 34, is on a boob baring barrage...or something. First she did that racy ad for PETA (which actually showcased her crack; but also featured a smidge of side boob). Then she went all out in the May issue of Vogue Italia. And now she's in this commercial for Calvin Klein's Secret Obsession, which, thanks to a brief cameo made by Mendes's nipple, you won't be seeing on TV in the U.S. (not the uncensored version anyway).
