Tricia Helfer (BSG)
Evangeline Lilly (Lost)
Yvonne Strahovski (Chuck)
You know that these three are mega hotties when Tricia Helfer finishes in third place.
Helfer is super hot as a Cylon in BSG, but for me, she is a bit behind the other two.
Now, if you asked me three years ago who was hotter than Evangeline Lilly, I would find it difficult to come up with an answer. "Freckles" has one of the best bodies I have ever seen, and even though she was dating that Hobbit guy, I couldn't hold it against her. If I ever met him, I would probably kill him and take his body to a lab to be dissected. Then we could find out what type of weird scent he was releasing that would make a girl like her want to have sex with a guy like him.
But then one day a crazy thing happened, I started watching a show about a nerd working at Best Buy. When I first saw Yvonne Strahovski, I actually wasn't that impressed. I thought she was just another hot blonde, but that was about it. But as she kicked ass in skimpier outfits every episode, my lust meter went through the roof. I know it's weird to say, but her character changed my perception of her. At times she had that innocent fuck me look. Then it was an ass kicking fuck me look. Other times it was a stern fuck me look. Her fuck me look range was off the charts!
So to sum up, Strahovski would be my choice at the moment barely edging out Lilly. This could change as easily as the direction of the wind, but that is my final answer today.
