Katy Perry stripped down for the September issue of Rolling Stone, looking uncharacteristically demure, opting for regular old pink lingerie instead of glow sticks and other outlandish accessories. Certainly the singer, whose infectious new single "Teenage Dream" has been pumping on our headphones recently, looks pretty! But where's her candy-coated, David LaChapelle–like, flamboyant aesthetic? Perhaps she left it in Malaysia last weekend on the MTV World Stage, where she rocked a tutu and sparkles while performing inside a giant banana split. That's the Katy Perry we know!
