I admire both of these stars. I think these two were pretty close match since it took me a while to decide who I am going to choose. I love a lot of Rihanna's songs, and although she certainly has a way of exposing herself and dressing, I think she's pretty amazing. Amy Adam's I've been a fan of for ages. I did know that she was extremely talented and is able to sing really well. She tends to stick to acting however and she's just as sexy. Close fight here, but I choose Amy.
