The track is believed to be taken from the singer's forthcoming new album, set for release earlier next year.
"I want to take enough time to make sure it's the reinvention of pop music," Ke$ha said. "That's the ultimate goal, to reinvent pop music.
"So I'm planning on taking as much time as I need, but May sounds about right."
Ke$ha embarked on a short UK tour earlier this year as well as performing at Glastonbury festival back in June.
