Picture stills from the 'making of' California Gurls music video shows that Katy Perry was indeed nude on the production set. (Katy Cocktease, as we call her for constantly showing the world 90% of her body, while hiding the 10% she knows we all want to see.) I think you know my feeling on this subject: Katy, we will buy your craptastic music (even the Spice Girls would've been embarrassed to sing California Gurls) but we want to see your fantastic big boobs. And, no, not the fake ones circulating on the Internet.
