Apparently, EMI still isn't done milking singles out of Katy Perry's One of the Boys. "Waking Up in Vegas" is Perry's latest, and its accompanying clip throws out all of the Las Vegas stereotypes that one would expect, as well as affording Perry the opportunity for several costume/wig changes. You have to hand it to Perry for one thing though: "Waking Up in Vegas" is her first single that passes by without a single note of casual, callous homophobia. She must be growing.
