Either Lee DeWyze, left, or Crystal Bowersox will be announced as the winner of the ninth series of American Idol tonight Finalist: From 100,000 hopefuls, either Crystal or Lee will be crowned American IdolThe 24-year-old's energy had been lacking in recent weeks, but she made a storming come-back, while Lee appeared to have lost some of the confidence that had seen him emerge as the competition's dark horse.'This is one of your best moments, at a perfect time' judge Randy Jackson told Crystal after she closed the show with an emotional rendition of the contemporary folk-gospel song Up To The Mountain.'You took that song and you absolutely nailed it,' the usually abrasive Simon Cowell told her after her version of 1990s rock classic Black Velvet. Final show: Simon Cowell is leaving American Idol, to launch the X Factor in the U.S. next yearLee had been tipped by Cowell to win before Tuesday's final performances in front of 7,000 fans.But the bluesy singer and guitarist, who a year ago was working in a Chicago paint store, seemed to have lost some of the confidence that saw him overshadow Bowersox last week.'I would expect a lot more passion and excitement.
