Katy Perry is an American singer, songwriter. Kathy Perry was born in Santa Barbara, California, USA. The middle child of two pastors, she grew up listening to gospel music and singing in church. After Steve Thomas and Jennifer Knapp signed Perry to their label Red Hill Records, she released her first CD Katy Hudson in 2001, a Christian gospel album.

After signing to Capitol Records, Perry began recording for her official mainstream debut album, released in 2008, working with Greg Wells, Dr. Luke, Butch Walker, Max Martin, Cathy Dennis, Dave Stewart, and Ted Bruner. The full length album titled One of the Boys was released in the USA on June 17, 2008. Katy was an act in the 2008 Vans Warped Tour to promote the album. The album was preceded by a digital EP in late 2007, entitled "Ur So Gay", produced by and co-written with Greg Wells. A video for the song premiered in early 2008, and brought Perry to the attention of Madonna, who mentioned her on KISS FM & KRQ's JohnJay & Rich morning show in Arizona, stating that "Ur So Gay" was her "favorite song right now," as well as another mention on Ryan Seacrest's Morning Show. "Ur So Gay" has been criticized for alleged homophobia.

On April 29, 2008, her first official single from one of the Boys, "I Kissed a Girl", debuted on the iTunes Store. The song debuted on the Billboard Hot 100 at #76, climbing to #1 as of June 25, 2008. It has peaked on iTunes Top 100 at #1, as of June 3, 2008. The music video for "I Kissed a Girl" was released on May 21, 2008 on MySpace. The song has generated controversy due to its popularity with children and its depiction of sexuality, homosexuality, and promiscuity. In contrast, an essay in Slant Magazine argues that the song "isn't problematic because it promotes homosexuality, but because its appropriation of the gay lifestyle exists for the sole purpose of garnering attention—both from Perry's boyfriend and her audience." As an actress, she made a cameo appearance on Carbon Leaf's video "Learn to Fly" and on Gym Class Heroes' video "Cupid's Chokehold", playing the eventual love interest for her real life boyfriend, lead singer Travis McCoy. On March 10, 2008, she appeared as herself on ABC Family's Wildfire. She has appeared in advertisements for Too Faced Cosmetics' spring 2007 line. On June 12, Perry appeared as herself on the popular daytime soap opera, The Young & the Restless, who poses for the cover of the fictional magazine Restless Style, and on MTV's TRL.

This year her single "I Kissed a Girl" has become a worldwide hit, topping Billboard Hot 100, Canadian Hot 100, the UK singles chart, the Australian ARIA Charts, and peaking at #2 on the Worldwide Charts. This single is second single from the album “One of the Boys” produced by Dr. Luke. The music video for the song was directed by Kinga Burza features a Moulin Rouge and burlesque-type setting with scenes containing Katy, along with many other flamboyantly-dressed women, dancing to the song. The video made its television debut on June 12 on TRL with the visit and interview by Perry in set show. And on June 24, 2008 it became #1 on TRL. It debuted at #20 on VH1's VH1 Top 20 Video Countdown on June 28, 2008. On June 30, 2008 the video was premiered on MTV Latin America.
