Nymphet nature: With a model mom and a rock star dad, it's not surprising that Liv turned out mature for her age. The teenage model turned actress (along with fellow jailbait accomplice Alicia Silverstone) first pole-danced her way into MTV watchers' hearts in the video for Aerosmith's "Crazy." Creepy? Yes. Smash hit? Also, yes. And in "Empire Records," she attempts to use her sex-kittenish ways (via cropped Angora sweaters) to seduce the douchey, aging rock star Rex Manning.
