Ke$ha has revealed that she has had sex with a ghost but that she didn’t know his name but she was ‘very open to it’.

The American singer said that her new track ‘Supernatural’ was inspired by an erotic paranormal experience.

“It’s about experiences with the supernatural… but in a sexy way,” she told Ryan Seacrest on his KIIS FM radio show.

“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 added that her new album Warrior was based around a spiritual quest she went on to improve her music.

“The theme of this record is magic. I went on a spirit journey by myself,” she said. “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.

“I got hypnotised, and I just really wanted this record to be really positive, really raw, really vulnerable and about the magic of life.”

OK… excuse us for being prudes but isn’t that a little wrong, and also… well if you believe in ghosts we suppose you can fancy them as well. One only hopes he’s not the possessive type.

The Black Keys’ drummer Patrick Carney, The Flaming Lips’ Wayne Coyne and Iggy Pop will all feature on Ke$ha’s new album. The album, which is the follow-up to the eccentric singer’s 2010 debut LP ‘Animal’, will be released on December 3.
