Angelina is an avid butterfly collector and flipper. She flipped a bali on Late Night with Conan O'Brien, when, knowing she was into balis, Conan produced a bali form under his desk and asked her to demonstrate with it. She didn't seem very good, but I'm sure she was probably both nervous and caught a little off guard.
