Katy Perry has promised "a little haunted something" for her fans to celebrate Halloween tonight (31st October).
The 'Teenage Dream' singer is due to play Manchester's MEN Arena tonight, and has revealed that she will be marking the spooky day in style.
Katy told Capital FM Showbiz reporter Kevin Hughes: "I have a show on Halloween, which I'm kind of like, 'Cool I'm excited about the show', but Halloween is one of my favourite holidays.
"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."
