Recognize Ke$ha on the red carpet?
No, we didn't either.
The usually wild, glittery pop star revealed what's being called her most "shocking look yet" at last night's American Music Awards.
Shocking because she looks, um, normal!
But when she hit the stage, Ke$ha was back to her usual style, ramping it up for her performance of Die Young.
While her looks may have been more demure than usual, Ke$ha was as sassy as ever in interviews. When Entertainment Tonightasked if she would be interested in dating Justin Bieber, 18, in thewake of reports he has split from Selena Gomez, Ke$ha, 25, answered: "Imean, is he of age? I would hit that. Who wouldn't hit that?"
