JAMIE PRESSLEY SECRETS

My Name Is Earl beauty's bulimic past.

Jamie Pressley admits she was desperate to stay thin as a young model starting out, she puked up everything she ate in a frantic attempt to keep her weight down.

But a childhood pal saved Jamie's life as she writes her in shocking new tell-all memoir It's Not Necessarily Not The Truth.

"Dawn was going into my bedroom to grab something and she walked past the bathroom and heard me (puking)," Jamie confessed.

"(She) went and got her boyfriend and her boyfriend busted the door down and said, 'You will not, absolutely not, do this!'"

Jamie realized that when she saw the "fear in their eyes" she knew she had become obsessively self-destructive in her quest for illusory perfection.

Now, eating sensibly and working out is what keeps Jamie on the right track to health along with her zany hi-jinks on the very successful hit comedy Earl.
