Amy Adams is the boner-creator actress! She is so sexy, when you see her the only thing that comes to your mind is how she would look like naked. And guess what, she did some naked scenes. A pic from the most famous is below.
But that one is just most famous, she had several sexy and naked appearences on screen besides the one above, which is from the movie Psycho Beach Party btw. She had another naked scene in 2008 movie Sunshine Cleaning and same year in Miss Pettigrew Lives for a Day. The next boob shot is from Sunshine Cleaning.
I know a few pictures are lame, of course there's a place online where you can see the full scenes & whole picture sets. In fulscreen and most of them also in HD. That place is called Mr. Skin.
