Katy Perry Looks Purr-fect in England Before Halloween Gig (PHOTOS)
During the interview, she admitted tonight's show will be full of spooky surprises.
"I'm planning a little something. You know me I've always got a secret surprise up my sleeve for a little haunted something. It's been a very spooky month."
Last week, Katy was all business in black pants, a white short-sleeved button down and bow tie as she took a break from her UK tour to perform live on last night’s X Factor.
Mrs. Russell Brand recently ditched her natural blond locks and went back to a funky pink hue when she touched down in Londontown late last week. For the performance, Katy strummed on a guitar for an acoustic rendition of her latest single, The One That Got Away.
