Ke$ha had sex with a ghost… no seriously, she said she had sex with a ghost!

The “Die Young” singer revealed her not so normal one night stand while on Ryan Seacrest’s KIIS FM radio show.

While on the show, Ke$ha admitted that the inspiration for her new upcoming song “Supernatural” comes from a sexual experience she had with a ghost.

“It’s about experiences with the supernatural… but in a sexy way,” she told Seacrest. “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.”

Oh, okay Casper!

The 25-year-old also revealed that her new album Warrior was inspired by a spiritual quest she took in an effort to improve her music.

“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 explained. “I was in Africa rehabilitating baby lions. I went diving with great white sharks, and just went on this crazy spirit quest.”

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

That just sounds like a vacation… I need a spiritual journey ASAP!
