In a recent interview with Ryan Seacrest, Ke$ha confessed to having had sex with a ghost, and revealed that this alleged paranormal rendezvous inspired her new track "Supernatural." Sadly, we might never know if Ke$ha's spectral lover was the ghost of anyone famous: "I don't know his name! He was a ghost!" she said, adding that she's "very open" to "experiences with the supernatural." Maybe it's not that surprising that someone who sings about brushing her teeth with whisky would be into spirits.
