Kat lets it out of the bag.

Katharine "Cleavage" McPhee will again follow in Taylor Hicks’ footsteps when she graces this week’s People Magazine, revealing that she used to battle bulimia, according to entertainment news program Extra! (http://extratv.warnerbros.com/v2/news/0606/21/2/text.html).

"She was throwing up seven times a day," Jamie Bufalino of People said, describing Katharine’s confession about her struggle and her belief that the timing of American Idol forced her to face her body image and food anxieties. "When she got to Idol, that's when she got serious." It was at that time when Katharine reached out to a Los Angeles area eating disorder clinic for help.

"I was always trying to lose weight and then I was obsessed about the food," Katharine said the night before the AI finale, hinting at what she is now sharing publicly. "As soon as I stopped worrying about the food, the weight just started coming off." Katharine has shed approximately 30 pounds and three dress sizes. She credits the support she gets from her parents and boyfriend Nick Cokas with helping her lose weight the healthy way and will showcase her fabulous form on the cover of the next issue of Teen People.

"I'm very honored that people say I'm a role model for young girls," Kat said. No need for Kat to wonder then, as Taylor might say, "Do I Make You Proud?"
