Biggest Controversy: Carly Rose Sonenclar and LeAnn Rimes
Thirteen-year-old Carly Rose Sonenclar was so flawless all season, people called her an alien, a robot and just plain amazing. But during finale week, that all came to a screeching halt when her duet with LeAnn Rimes went horribly awry. While performing "How Do I Live," Rimes looked seriously disheveled – and sounded just as bad. Their voices didn't jell, and for the first time Carly Rose sounded, well, off. The Internet soon lit up with conspiracy theories about Rimes being inebriated. And then the blame game started – Rimes reportedly said Carly was "nervous" and "having trouble hitting the right notes," which threw her off. When Carly lost to Tate Stevens, people speculated it may have had to do with the way Rimes handled the whole situation.
