Kiedis acknowledges in his autobiography Scar Tissue that he had sexual relations with raped a 14-year-old girl when he was 23, before and after learning of her age, in the 1980s. This inspired him to write the song “Catholic School Girls Rule”.[121]
Kiedis had a relationship with actress Ione Skye in the late 1980s starting when he was 24 and she was 16.
