Katy Perry reveals the 'weird thing' she does before getting into bed: 'I swear by it'

Katy Perry is the latest subject to spill her favorite products for British Vogue's In the Bag series.

The 39-year-old pop star — who just dropped a music video for her song Lifetimes — toted a large, black Hermès bag for the six-minute clip showing fans what she regularly carries around.

'I swear by my lint roller,' she declared after pulling it out and giving her figure-hugging black dress a swipe.

The California Gurls hitmaker then revealed, 'I will lint roll the bottom of my feet before I get into bed.'

She endearingly added, 'Is that weird? Do we all have weird things like that? I think we do. I just shared mine with the world.'

Elsewhere in the clip, the music artists rattled off which beauty products she loves.

Among them was Turmeric Glow Moisturizer by Kora Organics, which was founded her fiancé Orlando Bloom's ex-wife Miranda Kerr.

She referred to the model as 'our modern family mother' and called her 'a good friend of mine.'

'She has created this incredible moisturizer that I've gotten everybody in my team hooked on,' Katy gushed.

The star added, 'It makes you feel sparkly and glowy and I have it on now.'

The Dark Horse singer also praised a Solawave light therapy wand, which she confessed she 'stole' from Orlando's Golden Globes gift basket.

Bringing up parenthood — Perry and Bloom share daughter Daisy, four on August 26 — she said the contents of her purse have changed since she became a mom.

'[I] always have a snack, always have water for her. Always have, like, a little toy or something that she can play with,' the proud mother said.

Katy also pulled out her child's adorable, pink Hello Kitty watch.

'She's really into Hello Kitty right now,' the star, born Katheryn Hudson, shared. 

The raven-haired beauty added, 'She's going to be four and I'm thinking maybe her next birthday theme is going to be Hello Kitty.'

Perry later whipped out a pair of sparkly silver ballet slippers with the cartoon character's face on the toes.

'If I'm in my heels and I've had a long day, I'm pulling out my flats,' she said while holding up the footwear.
