Turns out Katy Perry’s blue “California Gurls” wig is also her blue “Teenage Dream” wig. (Brava for recycling, Katy. Perhaps a green wig is in order next?) This sleeve (click “more” below to see the full thing) for her upcoming single was offered up yesterday, after we first caught a glimpse of the waterlogged pop singer engaged in a lovey-dovey nightswimming session from the song’s upcoming video. The unveiling of Perry’s Teenage Dream album cover is expected to happen today.
