It would be too much of a coincidence for a girl that looks just like Katy Perry to have the same body proportions. Not to mention that totally looks like a Katy Perry bath room. She is always wearing those bright green and purple colors.
I am further convinced that this is a naked picture of Katy Perry because of the expensive looking camera being used. Only someone like Katy Perry, who fancies herself an “artist”, would spend money on a camera like that. She then realized that taking black and white pictures of flowers is boring, so she went into the bathroom and took a naked picture of her self.
All the evidence points to the fact that this is a picture of Katy Perry naked. I have to say Katy has really raised the bar with this photo. It is your move now Lady Gaga.
