Monica Bellucci definetly exudes class. If you look at the way their makeup is applied, though it is the same look (smoky eyes, pale lips), Monica Bellucci looks more refined, whereas Kim's makeup leans more towards that whole "tan skin/dark eyes/peachypink huge lips" porn look. There is something about her features (maybe the lips?) that screams fake. Gotta love her hair though. She has the shiniest hair I have ever seen.
By the way, that picture posted above of Monica Bellucci, with the deep décolleté: Hubba Hubba. That woman is smoldering wow! See how sultry she looks without entering the slutty zone?
