Can You Guess the Celebrity Cleavage?

Today's mystery rack belongs to a 32-year-old TV and film star who hails from Los Angeles, CA.

She is the lovechild of a former Aerosmith guitarist and and exotic dancer, and was scouted by a former Playboy playmate, who placed her in a medical office where she would work in exchange for a breast augmentation.

She later declined the procedure, and was subsequently fired, but from where we're standing, she clearly didn't need it. She landed several small roles before landing one in 2006 that made her a household name.

Clear dress, full breasts, can't lose! Any guesses?
