Los Angeles, Aug 10 (IANS): Singer Katy Perry has opened up about her weird nighttime routine, which involves cleaning her feet with a lint roller before she hits the sack.

"I swear by my lint roller. I will lint roll the bottom of my feet before I get into bed. Is that weird? Do we all have weird things like that? I think we do. I just shared mine with the world," Perry said on British Vogue's 'In the Bag' video series.

The “Roar” hitmaker, whose fiance is actor Orlando Bloom, said that, these days, a lot of the space in her bag is given over to her daughter's essentials, reports femalefirst.co.uk.

She said: "(I) always have a snack, always have water for her. Always have, like, a little toy or something that she can play with."

Perry also "swears by" a red light therapy wand. However, she "stole" the "handy" gadget from her 47-year-old partner.

She said: "When I'm not wearing make-up, I do some skin prep. Okay, I swear by this little guy. I stole this from Orlando's (Golden) Globes gift basket. It's just this little pen, and it's so handy, dandy.

"Turn it on. And it's red light therapy. And I just go up, up, up. I'm doing work, I'm taking calls. Red light therapy just helps create more collagen, I think, and bring your skin back to life. Health is wealth."

She credited Bloom for being the reason why she carries around so many different vitamins and health supplements.

Perry said: "Orlando is very healthy, like annoyingly healthy."
