Taylor Swift - Better than revenge?

it's about Camilla Belle because she stole Joe Jonas, she went to a prep school, she wears vintage dresses, Joe wrote Much Better about Camilla and Taylor (hence the part where Taylor sings "see you deserve some applause, cause you're so much better), she's an actress, the part "she's better known for the things that she does on the mattress, woah" Camilla is known as a whore. And " I think her ever present frown is a little troubling" Camilla usually is frowning.
