Wasn't it in some kind of poll? The woman most mentioned by straight women as the prefered partner for some kind of same sex sexual act was Angelina Jolie. I think it's the fact that she is comfortable with the fact that she's bisexual and has kissed females in public that let women know, all women who have open sexuality aren't always adhering to a certain image. They can infact be stunningly gorgeous and proud of it.
