Sometimes, the trappings of fame come with dangerous addiction problems. With all that money and all that partying, there's a constant temptation to spiral into drug and alcohol issues. Ke$ha, though, has an addiction of another kind. She just can't get enough glitter. She apparently spends in excess of $10,000 per month on it. It's not uncommon for someone to coat their outfit - or even their skin - in glitter for a big night out, but Ke$ha apparently likes to be covered in the stuff 24/7.
In an interview with Vanity Fair, she admitted that she no longer spends as much on it as she once did, but still considers it an essential part of her beauty routine, and often pairs a full-body glitter treatment with a manicure appointment. At one point she even had a full-time member of staff to ensure that she was always covered in glitter.
