The post, which purports to be from a woman who wore "blue hair, silver tube top, fishnets, (and) knee high black biker boots" to the recent concert at the Aragon Ballroom, is seeking a red-mohawked man with "black pentagram gauges" and "viper piercings" who engaged in a bathroom tryst with her during the show, the Chicago Sun-Times reported Friday.
"Anyway, I'm pregnant. It's yours. Contact me, if you want to be part of the child's life," the posting ends.
It is unknown whether the couple have reconnected or whether the entire posting was a hoax, the newspaper said.
