Taylor Swift is a pretty girl. No one ever said, “Taylor Swift is not a pretty girl.” However, with that curly, high school hair and songs about princesses and Romeo and Juliet, it’s easy to forget that she’s 21 years old and should be reaching the sexy-peak of her adult life.

But this weekend, at the AMAs, she seemed… Different. And maybe it was the straight hair or the cleavage-friendly dress, but Taylor Swift was looking about as sexy as any blond country star could. We bet John Mayer is kicking himself as we speak.
