Liv Tyler's teenage mix-up over her two dads was so bizarre even her therapist was stunned. The actress struggled to come to terms with the fact that rocker Todd Rundgren wasn't her real father and the Aerosmith star she idolised, Steven Tyler, was - and the realisation sent her to therapy. She says, "I had such a complicated growing-up experience, with my dad and stepdad and the therapist was literally just sitting there like she couldn't believe it all. "I actually shocked the therapist with my life story."
