Kesha spends "thousands" of dollars on glitter every month.
It's pretty exorbitant. It's probably more like a few thousand (dollars) every month.
The eccentric singer - who has previously revealed she gets naked and rolls around in the sparkly make-up before concerts - racks up huge glitter bills even though her fascination with it annoys her friends.
She said in an interview with Vanity Fair magazine: "It's pretty exorbitant. It's probably more like a few thousand (dollars) every month.
"If you come and see a show of mine, there is no shortage of glitter. I am shooting glitter from glitter guns and out of every orifice in my body.
"It's my goal to cover the planet in glitter and take the f**k over. I can't do that if I don't have a s**t-ton of glitter.
"When you're around me, you're going to get glitter on you. It infuriates a lot of people who hang out with me. They get glitter on them and it won't come off for days and it ruins their game.
"I've found glitter in places that will not be named. It's coming from everywhere on my body. Let's just leave it at that."
The 23-year-old singer was given a tattoo gun for Christmas by her management team but is disappointed because none of her friends will allow her to try it out on them.
She said: "I was with my hairdresser when he said he wanted a tattoo, so I whipped out my new tattoo gun. It's really loud; it makes this whirring noise like some scary electronic mouth drill from the dentist. He got really freaked out and said, 'No, no, no, just give me an old school tattoo.' So I whipped out a sewing needle and ink pen, and I gave him this tattoo."
