Pouty, doe-eyed Liv Tyler first drove men nuts paired with the wickedly wanton Alicia Silverston in Aerosmith's "Crazy" video. The two young vixens rode that wild trip to superstardom. Liv's big-screen debut was Heavy (1995), but she didn't show her heavy hitters until later that year in a slightly skinful spread in Playboy. It wasn't until Bernardo Bertolucci's Stealing Beauty (1996) that we got a glance at her sweet beauties onscreen. Since then, Liv has shown little interest in disrobing, although she's cut a sexy figure in fare such as Armageddon (1998), Dr. T and the Women (2000), and One Night at McCool's (2001). Perhaps best known as Arwen, the elf princess who gets hot for man meat in The Lord of the Rings trilogy, this magical enchantress makes Mr. Skin take Liv of his senses.
