American Idol's judge Simon Cowell called contestant Katharine McPhee's voice "the best of the competition." What hardly anyone knew, however, was that she'd risked destroying that voice: She'd struggled with bulimia for five years, and the self-induced vomiting could have taken away her ability to sing.
At her worst point, she was throwing up as many as seven times a day, which is like "putting a sledgehammer to your vocal cords," she told PEOPLE.
Finally, after successfully auditioning for American Idol last fall, Katharine, 22, decided to seek help.
She said:
When I made it onto American Idol, I knew that food – my eating disorder – was the one thing really holding me back, 
I was bingeing my whole life away for days at a time … So when I got on the show, I said, 'You know what? I can do well in this competition. Let me give myself a chance and just get ahold of this thing.'
