Singer Kelly Clarkson suffered from bulimia after missing out on a role in a high school musical. The “American Idol” star spent half a year battling the eating disorder, according to Star Pulse.

"I thought if I come back and I'm cuter and thinner... then I'll get the role. I became bulimic for the next six months. One of my guy friends caught on to it, and I just felt so ashamed and embarrassed," she told the upcoming August edition of U.S. magazine Cosmo Girl.

However, Clarkson ended her bulimic suffering without outside help. "I literally went cold turkey and snapped out of it," she added.
