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.
She tells the upcoming August edition of US magazine Cosmo Girl: "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."
However, Clarkson ended her bulimic suffering without outside help.
She adds, "I literally went cold turkey and snapped out of it."
