Katy Perry
Katy Perry is honest about her unsanitary habits, but she also doesn’t care what others think about them. She is constantly leaping and jumping during her performances, which she claims has increased her flatulence. It sounds like a lot to disclose in an interview, but we did learn what Katy and Orlando (also featured here) shared in common. Many celebrity couples have developed unsanitary habits, and it appears that these two are no exception.

Kim Kardashian
Kim, unlike the other celebrities on our list, maintains her cleanliness by showering on a regular basis and washing her hair twice each week. Showering and washing hair are insufficient indicators of someone’s hygienic standards, as you’ll discover with Kim. Most people will tell you to take off your makeup before going to bed since it will go on your bedding and pillows, causing acne. Kim, on the other hand, believes in sleeping with makeup on since she is too busy to apply it in the morning.
