"Her aide said the gear had to be robust as they were-taking it on the road," the owner of the ghost-busting gear told the paper, "so they must be doing this everywhere Lady Gaga is performing." Several months later, Gaga still felt spooked and held a séance to scare away the ghost, whose name is reportedly Ryan. As a source from her tour explained: "She's pretty terrified by this spirit, but more than anything he's annoying her as he won't leave her alone. He hasn't been doing anything too violent or scary, but she's freaked out by his presence."
