Singer Katy Perry was photographed yesterday parading to and from a Hollywood studio in some revealing dance togs.  She was sporting black lacy tights and a skimpy grey leotard.

The musician was a guest judge last night on American Idol and managed to butt heads with Kara DioGuardi.  We're not sure if their little feud was trumped up or a real clash between divas.  Check it out on video below.
