Katy Perry may not be supporting herself the old fashioned way in this handful of promo pics for Teenage Dream—but this double set of photos are still a feast for the eyes. In her Victoria Will photo shoot, Katy makes all the girls green with envy while wearing a tight-fitting emerald dress, looking as dangerously sexy as Poison Ivy. And in some bright-and-bubbly promo pics, KP rocks her favorite wig with some fabulous fluorescent latex and neon hippie-wear. We love the look, love the songs, love this gurl.
