Ever since the November 2007 digital release of the hilarious, zeitgeist-capturing single "Ur So Gay," Los Angeles-based singer-songwriter Katy Perry has been wowing critics and fans alike (including the Queen of Pop herself, Madonna) with her big voice, sassy attitude, and feisty, confessional songs. Katy's debut album, One of the Boys, is a sharp, witty pop-rock gem filled with candid tales of neurotic ex-boyfriends ("Hot N Cold," "Ur So Gay"), crazy road trips with friends ("Waking Up in Vegas"), and figuring out who you are along the way (first single "I Kissed A Girl," "Fingerprints"). While the album displays Katy's feisty, girl-power swagger, it also reveals her more vulnerable side on such regretful ballads as "Lost," "I'm Still Breathing," and "Thinking of You." Although just 23, the Santa Barbara, CA-born native has been writing songs and playing guitar for several years, and possesses the flair and confidence of a veteran storyteller. Catch her in all her glory this summer when she joins the Vans Warped Tour for its entire coast-to-coast run.

Teenage Dream is the third studio album by American singer-songwriter Katy Perry. It will be released on August 24, 2010 in the United States.It will be her second mainstream pop album, following her pop debut album One of the Boys. The album's lead single titled "California Gurls" featuring Snoop Dogg was sent to US radio on May 7, 2010.

"California Gurls" serves as the lead single of Katy Perry's upcoming sophomore studio album. The song features rapper Snoop Dogg, and was produced by Dr. Luke, Max Martin, and Benny Blanco. According to Perry, the song is a answer song to "Empire State of Mind".
During a Rolling Stone photo shoot in April 2010, Perry revealed details about the song, allegedly a response to Jay-Z's "Empire State of Mind", she stated: "It’s so great that 'Empire State of Mind' is huge and that everyone has the New York song, but what the f**k? What about LA? What about California?. It's been a minute since we had a California song and especially from a girl's perspective. We took the references of Prince, which is always a great reference, and some of the '90s, almost house music references".
After the song was leaked online, Capitol Records decided to release it early, and it was posted on Perry's newly revamped site due to the song, and the radio release date was moved up from May 25, 2010 to May 7, 2010.[2] The artwork was also released, featuring Perry laying out on the beach sand with a bejeweled bikini.
