Kesha rocked the orange carpet with her little brother, Louie Sebert, dressed as Harry and Lloyd from 'Dumb and Dumber,' but there was nothing dumb about her performance. The girl can rock out like no other!

Sporting neon yellow and faux fur, with her long blond hair in a high ponytail to showcase her cute mug, Kesha changed the lyrics of 'We R Who We R' from "sick and sexified" to "sick and sassified," accommodating the younger crowd. After launching into a chorus and first verse of her 'Cannibal' hit, the cannibal queen launched into 'C'Mon.'

Though 'C'Mon' is basically an ode to one night stands, K-Dollar Sign kept it clean, muting herself at racier parts of the track and changing "screw around" to "mess around." Kesha may not give an eff about a lot of things, but she's considerate of her audiences.

Rico Rodriguez begged for a doctor after her performance to fix his "Kesha fever," while Nick Cannon requested "extra Keshup." We don't blame him -- she's delicious!
