Hottest 30 Under 30
#5. Katy Perry (27)
Katy Perry has turned candy into fashion, added a sense of humor to the pin-up look and made chart-topping look way easy. The Cali native has been on everyone's radar since her girl-kissing days, but she made history this year by tying the record with Michael Jackson for most #1 singles from one album. Perry also boasts two fragrances, and just released her own 3-D popcorn flick. This girl's bucket list has to be finished by now, no?
