Taylor Swift

Taylor Swift kinda came out of nowhere to become one of the most powerful teen celebs around. She wasn't even ranked on Forbes Most Powerful Celebs list last year, now she's at the 12 spot. The country cutie made $45 million from June 2009 to June 2010, and was the most-played artist on the radio in 2009. Her CoverGirl and Sony endorsements gave her a big boost, as well as the 3.2 million copies of Fearless her fans bought, legally.
