Ke$ha has claimed that she once had sex with a ghost.
During an interview with Ryan Seacreast on his KIIS FM show, the Die Young singer revealed that Warrior album track Supernatural was inspired by her intimate paranormal experience.
She told Seacrest: "It's about experiences with the supernatural... but in a sexy way.
"I had a couple of experiences with the supernatural. I don't know his name! He was a ghost! I'm very open to it."
Ke$ha went on to admit that her forthcoming LP is based around the 'spiritual' journey she completed in order to improve her music.
The star explained: "The theme of this record is magic. I went on a spirit journey by myself. No security guard. No managers. I just went around the world and lived on a boat.
"I was in Africa rehabilitating baby lions. I went diving with great white sharks, and just went on this crazy spirit quest."
The Tik Tok hitmaker added: "I got hypnotised, and I just really wanted this record to be really positive, really raw, really vulnerable and about the magic of life."
Producer Dr. Luke recently quashed rumours that Rihanna features on Ke$ha's new album, telling MTV News: "I'm going to tell you right now: there's no Rihanna.
"I don't know where that came from. I've seen it all over the place, but there's definitely not a Rihanna song on it."
Warrior is due for release in the UK on 3rd December.
