The singer's producer Dr Luke uploaded a 40-second clip of new track 'Supernatural', which is thought to feature on Ke$ha's upcoming second studio album.
Lyrics in the track include: "When you take my body to the stars/ I believe it/ Boy, this love is supernatural/ Can you feel it?"
Ke$ha recently revealed that she has teamed up with Sia to write new material for her forthcoming project and posted a picture of themselves in the studio.
The US star previously described herself as the "dirty little sister" of pop who "runs around with s**t on [her] face in combat boots because [she] can't walk in heels".
The follow-up to Ke$ha's Animal/Cannibal albums is expected to be released later this year.
