Why She's Hot: While her hit singles 'Tattoo' and 'No Air' are still fan favorites, the Season 6 'American Idol' winner is showing the world another dimension of herself on her sophomore album, 'Battlefield.' With pipes that won't quit, Jordin was invited to sing the national anthem at the 2009 NFC championship game and at the Commander-in-Chief's Inaugural Ball hosted by President Barack Obama. The Arizona native also supported the Jonas Brothers this year on their U.S. tour.

What's Up Next: Jordin Sparks is supporting Britney Spears on the second North American leg of her tour The Circus: Starring Britney Spears.
