Katy Perry is afraid of the dark

Los Angeles: Katy Perry has admitted that she is afraid of the dark.

The `Teenage Dream` hitmaker insists that she sleeps with the lights on unless she is with her fiance Russell Brand, DigitalSpy reported online.

"I think a lot of evil things go on in the dark. I still have to cover my toes because I`m like that kid who thinks there`s a witch under my bed who`s going to eat my tootsies off," Perry said.

"I sleep with lights on unless I`m with Russell," she added.

The 25-year-old singer has previously spoken of her fear of sleeping in cars, stemming from a childhood road accident.
