Hottest 30 Under 30
#11. Ke$ha (25)
Ke$ha is pop's favorite trainwreck, sing-talking about falling down drunk, stalking her crush (when she's not devilishly devouring him), and partying till you can't even remember the party anymore. But she's also an all-inclusive hot mess, welcoming any and all liberated souls to join her in her quest for sleaze, which is why she nabs a spot on our list.
