Ke$ha tweets photo of herself going 'pee pee on the street'

It's hard to know whether to be more grossed out by the photo Ke$ha tweeted of herself Wednesday -- showing her squatting down in what appears to be the middle of a street with her pants pulled down -- or the icky caption "pee pee on the street. PoPo come n get me if u can find meeee. I blame traffik." In response, one commenter asked the "TiK ToK" singer to marry him. Another sniffed "Pee-pee? Po-po? Cutesy talk does not give you class." A third echoed our own thoughts: "WTF!!!" To which we would simply add: Why?
