American Idol judge Simon Cowell has doomed a wannabe singer's chance of winning the TV talent contest by revealing he'll quit the show if he wins. The acid-tongued British judge admits he was stunned when contestant Sanjaya Malakar beat rocker Sundance Head for a place in the final 12 on Thursday night, and he'll leave the show if the Indian-American singer is crowned the next "American Idol."

Brutal Cowell says, "He's not going to win. I won't be back if he does!"
