Jordin Sparks, lady in red

We admit it -- we only watch American Idol during those first few weeks when it's the funny auditions, so we're not really up on Jordin Sparks' battle with her own image. She doesn't conform to Hollywood's image of a twig, but who cares when you look this hot! A high waist is ideal for gently flowing over curves and providing a slimming effect. That's hot.
