Ke$ha with a Mohawk: Awesome or Awful?

Ke$ha broke out a mohawk at last night's Us Weekly's Hot Hollywood: Stars Who Care event.
On any other celebrity, this might be a shock. On Ke$ha, we're almost surprised it took so long for her to make like Brody Jenner.

The eccentric singer said she did the 'do herself and:
"Even when I do dress up it's never like a pretty girl. I think it's more interesting to have a little of your [own] style in anything... I'm definitely not the hottest girl in the world by far, but, you have to work with what you got!"
What do you think of the hairstyle?
