Artist: David Archuleta
Age: 18

Why He's Hot: This piano-playing teen proves that you don't have to win 'American Idol' to be No. 1. Since the release of his self-titled debut, David has owned the charts with his hit singles, 'Crush' and 'A Little Too Not Over You,' and has been a Teen Choice Award favorite two years in a row. In 2009, he won TCAs for Choice Breakout Artist, Choice Love Song (for 'Crush), and Choice Music Tour (with Demi Lovato).

What's Up Next: David is finishing up his U.S. tour with Demi Lovato and gearing up for the release of his holiday album, 'Christmas From the Heart,' which is due out on October 13.
