The original ‘American Idol’ Kelly Clarkson suffered from bulimia after not landing a leading role in a coveated high school musical.

Kelly reveals in the August 2007 issue of 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.” “I literally went cold turkey and snapped out of it.”

(Hope Kelly’s doing better now, and knows that she has a beautiful figure! :)
