The pop star ditched her ripped stockings, studded hair and uhm, crude behavior, and channeled the 1920's in a very flapper-esque outfit. Ke$ha looked glamorous in a silver and gold drape dress, Jerome C. Rousseau black peep-toe heels and a thin gold headband placed atop her wavy blonde hair.
And it gets better: the singer's makeup was even appropriate, a far cry from her bright blue lipstick days, as she rocked shimmery eyes and wine-stained lips.
We're impressed! Is the "Tik Tok" singer finally trading in tattered flag shirts and her bottle of Jack Daniels?
Ke$ha did spring one beauty surprise on us, though: she used eyeliner as lip liner, which she gleefully tweeted about.
