Pop goddess Katy Perry appears on the cover of the February 2014 Love! Sex! Madness! issue of GQ US. Writer Amy Wallace catches up with the most-followed person on Twitter (49 million followers) moments before she goes full geisha at the American Music Awards. “I was thinking about unconditional love, and I was thinking: Geishas are basically, like, the masters of loving unconditionally,” she tells Wallace. They discuss her rise to stardom – and everything from ex Russell Brand and boyfriend John Mayer to her au naturel body and her relationship with Obama.
