Katy Soundtracks Summer With 'California Gurls'

In 2010, Perry needed a summer anthem to trumpet her second album, "Teenage Dream." She recruited Dr. Luke, Benny Blanco, Max Martin, Bonnie McKee and the coolest Cali native (Snoop Dogg) for "California Gurls," a celebration of everything West Coast and sand in stilettos. The bouncy pop confection became one of Perry's biggest hits ever, spending six weeks atop the Hot 100 and once again earning the singer Billboard's "Song of the Summer" crown, as well as topping Billboard's special "30 Summer Songs of All Time" list. Meanwhile, its "Candyland"-themed video -- especially the instances of whip cream shooting out of Perry's breasts -- remains iconic in the singer's career.

'Firework' Video Shines Bright for Acceptance

Upon its release in October 2010, the music video for "Firework," the third single and third No. 1 hit from "Teenage Dream," was declared to be in honor of the It Gets Better campaign, which combats harassment against those in the LGBT community. "I am officially dedicating my new video to #itgetsbetter, because everyone has the spark to be a FIREWORK," Perry posted on Twitter upon the clip's release. Reaction to the video was exceedingly positive: the official clip, which was filmed in Budapest and chronicles various characters trying to feel comfortable in their own skin, has collected 336 million YouTube views, at the 2011 MTV Video Music Awards, "Firework" was given the Video of the Year honor. Perry had successfully connected another pop hit with an important overarching message of acceptance.

Katy Enters the Perfume World


"Purr," Katy Perry's own fragrance, was launched in November 2010, just as Perry was enjoying her unstoppable run of "Teenage Dream" singles. With a bottle designed like a kitten and backing from Gigantic Parfums, Purr delighted Katycats and represented the brand extension of one of pop music's biggest stars. Perry launched a new fragrance, the similarly presented "Meow," in late 2011.
