Born in Portland, ME, on July 1, 1977, to model and former 1970s rock groupie Bebe Buell, Tyler spent most of her youth believing that rocker Todd Rundgren was her father. However, as she grew older, she began to notice more than a passing resemblance between herself and Aerosmith frontman Steven Tyler, who was a family friend, and she ultimately discovered that he was indeed her biological father. When she was 12, she took Tyler's last name as her own. Possessing an unusual beauty marked by perhaps the most distinctive set of lips in the business (an inheritance from father Steven Tyler), Liv Tyler unsurprisingly made her entrance into acting via the world of modeling. Since her breakthrough role in 1996's Stealing Beauty, she has emerged as a performer with bona fide talent, dropping her "model-actress" hyphenate in favor of just "actress."
