I suppose you could say Katy Cocktease is something of a pioneer when it comes to new and ingenious ways to flash some, but never all, of her flesh-fine boobtastic.
Down in Rio for the premiere of her concert documentary Katy Perry: You Still Can't See My Tits in 3D, the worldwide singing sensation, fresh off a nice bikini vacation in Miami we all got to enjoy, flashed a new cut-out top look that I think might show more cleavage than her normal 61% ratio, but in such a manner that we feel more teased than ever.
So, standard Katy Cocktease. But, still, undeniably, so hot. Enjoy.
