Kelly's always been one of the sweetest celebs out there, but who knew how much she does with the texture of her hair? She'll go from angelic ringlets to mermaid waves to stick straight at the drop of a hat. She's also unafraid to chop things off when she gets bored, and she never looks anything less than naturally beautiful. Her current style, which she showed off on David Letterman last night, looks like a great summery take on Janis Joplin's rocker-chic look, and I adore her aviators, but which style do you think looks hottest on our favorite American Idol?
