If you're a guy, and the one in the middle so much prettier it's stupid http://postimg.com/image/146000/msl-145313.jpg http://postimg.com/image/146000/mpf-145311.jpg
I think they're equally gorgeous in different ways :)
They both look pretty to me. The one in the middle is more feminine looking,so maybe that's why you're under the impression that she's better looking.
