Oh, Ke$ha, what were you thinking???
The 23-year-old “rebel” attended US Weekly's Hot Hollywood Event last night held at The Colony in Hollywood.
And for some reason she decided to go with that gray dress with fringe on the bottom and a crazy mohawk.
What do U think of Ke$has look last night?
And what about her dirty mohawk???
