The star explained that despite Iggy Pop and T Rex being her main influences, her second studio album won't be a rock collection.
"I want it to be a mix of what works on the radio and what I listen to in my spare time," Ke$ha told Rolling Stone. "I'm on a steady diet of T Rex and Iggy Pop.
"I'm not claiming that it's a rock record, but as long as it's f**king good, you can call it whatever you want."
The singer also admitted that the follow-up to her debut album Animal and its repackaged counterpart Cannibal will be more personal.
"The first two records talked more about partying, which is a great, magical part of life," Ke$ha said. "But some songs on the new record are more personal and vulnerable.
"And you can hear more of the music I listen to when I'm lying in my bed."
She continued: "Some people weren't sure if I could sing. On this record, I said, 'Let's leave the tricks to a minimum and let me wail'."
Benny Blanco - who has worked closely with Ke$ha on the new album - recently described the sound as "old hippie rock".
