31. Katy Perry
Katy Perry met her match this year when she and Russell Brand connected at the MTV VMAs — they were soon inseparable and got engaged around New Year's. She headed back into the studio to work on new music and recently released the first single "California Gurls" off her forthcoming album Teenage Dream. Katy also earns big bucks as a Proactiv spokeswoman, all of which helped earn her first ever spot on the PopSugar 100.
