Katy Perry is famous for more than a few things: her voice, her background, kissing a girl (and liking it!) and of course, her world-renown cleavage. Certainly, she's worn more than a few outfits that show them off, but none are as unforgettable as the whipped-cream, Super-Soaker edition from the "California Gurls" video. Fine, fresh, fierce, she's got them locked and loaded. As a tribute to our February cover girl, we took a panty-raid drive down memory lane to recall some of the world's most famous bras.
