LOS ANGELES, Calif. -- Mariah Carey is in the center of the spotlight right now with the release of her latest album, 'Memoirs of an Imperfect Angel,' and a breakout big screen role in the critically acclaimed, 'Precious,' but the singer's career hasn't always been hitting such high notes. In a new interview with Paper Magazine, the queen of the music charts says her infamous 2001 breakdown was linked to the events of September 11 and the public's inability to focus on what was important at the time.
