AceShowbiz - One of the most successful "American Idol" alums, Kelly Clarkson transformed herself from a nobody to a beloved pop star with her talent and hard works. But when talent and hard work weren't enough for her to thrive in the business, it cost her her peaceful state of mind. Opening up in an interview with Attitude magazine, the "Because of You" hitmaker revealed there was a huge pressure within the music industry to look a "certain way."

The pressure led her to develop an eating disorder and suicidal thoughts. "I was miserable, like inside and out, for four years of my life. But no one cared, because aesthetically you make sense," she said, and as a result, she "became thin." She added that people had no idea that she was "happy" because she "appeared healthy."
