'Die Young' is the lead track from the 'Tik Tok' star's upcoming second studio album. The song will be released later this month.
"Getting closer. Get hyped. Eternal boners," she tweeted.
She previously said of her new album: "The first two records talked more about partying, which is a great, magical part of life, 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. 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.
"On this record, I said, 'Let's leave the tricks to a minimum and let me wail'."
Ke$ha recently sang a snippet of 'Die Young' on a Tokyo subway. Watch the video below:
