She is the only daughter of Bebe Buell, a model, singer, and former Playboy Playmate (Miss November 1974), and Steven Tyler, the lead singer of Aerosmith. Her mother named her after Norwegian actress Liv Ullmann, after seeing Ullmann on the cover of the March 5, 1977 issue of TV Guide. She is of Italian, German, Polish, English and African American ancestry on her father's side and German ancestry on her mother's side. Tyler has three half-siblings: Mia Tyler (born 1978), Chelsea Anna Tallarico (born 1989), and Taj Monroe Tallarico (born 1991). Her maternal grandmother, Dorothea Johnson, founded the Protocol School of Washington. From 1972 to 1979, Liv’s mother Bebe Buell lived with rock musician Todd Rundgren. In 1976, Buell became unexpectedly pregnant from a brief relationship with Steven Tyler. On July 1, 1977, Buell gave birth, naming the daughter Liv Rundgren and claiming that Todd Rundgren was the biological father. Rundgren and Buell had by then ended their romantic relationship, but Rundgren nevertheless signed the birth certificate and acted as a father figure to Liv, including paying for her education.
