Liv grew up thinking that Todd Rundgren was her Dad until a chance meeting with Steven Tyler at the age of 10 made her suspect that the Aerosmith frontman was in fact her father.
Although Liv was not his child by birth, Todd Rundgren decided to care for her like a father and even signed her birth certificate, thus giving her the name Liv Rundgren. She gave birth to Tyler's daughter, Liv, in East Harlem, New York on July 1, 1977. Buell had a brief affair with Steven Tyler in the mid-1970s and got unexpectedly pregnant. Her mother was Bebe Buell, a model and former Playboy Playmate who was in a relationship with Rundgren throughout the 1970s.

Liv Tyler was an American film and television actress who was best known for her roles in 'Armageddon' (1998), 'The Lord of the Rings' trilogy (2001-03), and the HBO series 'The Leftovers' (HBO, 2014-17).
