A song i loved but can't remember the name or artist?

this song came out in the mid to late summer of 2009. it's a rock song sung by a woman and she sings about undressing in front of the window or something, and knowing its wrong, but she can't stop, something to that effect. i know i am being extremely vague and general, but thats all i can remember about this song. does anybody know what this song is? i love it and i really would love to hear it again, i lost my burned copy of that cd in a car accident last year. i appreciate the help!
