Pop star Ke$ha has revealed that a large portion of her tour budget goes on buying glitter. 

The singer, who is rarely seen on stage without cannons of the sparkling confetti, explained in Vanity Fair:

"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 asked how much she spends on it, she simply responded:

"It's pretty exorbitant. It's probably more like a few thousand [dollars] every month,"

The 'We R Who We R' star also told Rolling Stone that her next musical ambition is to gravitate "toward making a solid cock-rock record". Listen to her chart-topping track below:
