She's so angelic, we can't quite picture her playing a porn star!
Perhaps wishing to keep the sex appeal to a minimum, especially since audiences were about to see her engage in some VERY naughty acts, the 27-year-old chose a low-key premiere outfit.
Wearing black J Brand jeans, a striped Marni sweater, and a Michael Kors jacket, Amanda looked more like a pretty teenager than a deep-throating porn star.
Luscious curls and natural makeup completed her look.
