The `Tik Tok` singers` mother wanted her to be responsible and so from a young age encouraged her to act like an adult.
She said: "I knew everything about sex before I was even seven. My mom left me at home when I was 14 with a credit card, and a box of condoms and the keys to the car and said, `Don`t get pregnant and don`t drink and drive`.
"I had to be responsible for myself."
The singer also warned that her live shows have a particularly adult theme - including the audience being showered with Kesha condoms - and that her fans should expect to be "visually and sonically violated" by her shows.
She added: "I`m not a babysitter. My b**ls are on the table. I`m very upfront with who I am. There is sex. There is alcohol. The kids are gonna figure it out someday."
Kesha, who has two brothers, was raised by her mother in Nashville, US, and doesn`t know who her real dad is, so she pretends she is the offspring of the lead singer of The Rolling Stones.
She added: "I talked to my mum about it. She has a sketchy memory. I don`t really care. I`m going to pretend like my dad is Mick Jagger and proceed."
