It took less than a year for the folks on our Breakout Stars of 2008 to become household names. You may not have known them a year ago, but this year you couldn't get away. Robert Pattinson and his unruly 'do sent "Twilight" fans -- and then some -- swooning. Sarah Palin became the first hockey mom-pitbull to ever run for VP. Katy Perry kissed a girl, and radio liked it. (A lot). David Cook became the first angsty rocker to win "American Idol."
