Ke$Ha says she has had sex with a ghost, and tells the story about it in a new song "Supernatural".
One quick witted joker has since said it's proof she'd shag anything.
"It's about experiences with the supernatural," she told KIIS FM (via NME), "but in a sexy way. I had a couple of experiences with the supernatural. I don't know his name! He was a ghost! I'm very open to it."
The pop singer has recruited several rock stars for her new album "Warrior", which she once claimed would resurrect rock. They include The Black Keys' Patrick Carney, The Flaming Lips' Wayne Coyne and punk legend Iggy Pop.
"The theme of this record is magic. I went on a spirit journey by myself. No security guard. No managers. I just went around the world and lived on a boat," she said.
"I was in Africa rehabilitating baby lions. I went diving with great white sharks, and just went on this crazy spirit quest. I got hypnotised, and I just really wanted this record to be really positive, really raw, really vulnerable and about the magic of life."
Let's play a game: What else did Ke$ha do on holiday? Have fun in the comments.
