THE OC - BILSON'S DIRTY FACE THEORY

THE OC star RACHEL BILSON refused to wash her face when she was growing up - because she believed dirt would stop her from getting pimples.

The 23-year-old actress was so concerned with the way she looked, she was prepared to compromise hygiene for the sake of a clear visage.

She says, "When I was growing up, I would never wash my face. It really stressed my mom out.

"I had this theory, for some reason, that dirt kept pimples away. Then once I started to wash my face, I broke out. I was like, 'See, Mom?' I should've just stayed dirty."
