"California Gurls" is an electropop song by American singer-songwriter Katy Perry and is the lead single of her third studio album, Teenage Dream. The song features rapper Snoop Dogg, and was produced by Dr. Luke, Max Martin, and Benny Blanco. According to Perry, the song is an answer song to "Empire State of Mind" by Jay-Z and Alicia Keys. The song was originally intended to be sent to mainstream and rhythmic airplay on May 25, 2010. However, after clips from Perry's new album were leaked online, her label rushed the song to radio on May 7, 2010, and also began to stream it on her website. It was subsequently released to iTunes on May 11, 2010. The song peaked at number one on the Billboard Hot 100 for six consecutive weeks, giving Perry her second US number-one single and Snoop Dogg his third. The song reached number one in over 10 countries, including Australia, Canada, Ireland, New Zealand, and the United Kingdom. On December 2, the song received a Grammy nomination for Best Pop Collaboration with Vocals.
