According to the article, Ricci who's has plenty of experience playing sexually adventurous women, to put it nicely is a prude.
From the story: "I'm a prude and I do not like walking around naked and I was in my bathroom about two months after the movie finished and I was brushing my teeth and I was in my underwear and I looked down and was like, 'Oh, God, put something on.'
"Then I just stopped and thought, 'Oh my god, I was half naked for two months and my a*s was on camera.' "I called my sister and I was like, 'Is it OK to wear nothing around the house? I'm freaking out.'"
