Always one for pushing the envelope, Ke$ha did something very interesting to her hair for her 25th birthday. See her (robotic? punk-y?) transformation after the cut!

Personally, I think this is fun! For a woman who makes her money from singing about/rolling around in glitter, I think she's one of the few people who can pull this off. It's semi-edgy, interesting and just right for her. [via E Online]

What do you think of Ke$ha's new accessory?
