Kesha has confessed she feels like the "dirty little sister" of some of her fellow pop stars.
The Take It Off singer and rapper, known for her outlandish outfits and make-up, acknowledged she isn't quite as polished as some other singers.
She told V magazine: "I do feel like there are the pop stars of the world and then I'm like their dirty little sister, running around with s*** on my face in combat boots because I can't walk in heels."
The 25-year-old said part of what she is doing with her career is about her working-class roots.
"I was never the cool kid, I was never hot in high school. I was never popular. You don't have to be perfect and you don't have to be rich and you can still be successful," she said.
Kesha, who is preparing to unveil her next record, admitted that despite her success she likes to keep her life private.
She said: "When paparazzi showed up at my house, it was really mind-boggling. I've found ways to do exactly what I want, but in the privacy of my own sanctuaries."
The singer splits her time between houses in LA and Tennessee living in the woods.
"I have wild, wild nights there, but my friends and I are all really private. We get f****** crazy, but you're not going to see me stumbling out of nightclubs."
