Katheryn Elizabeth "Katy" Hudson, better known by her stage name Katy Perry, is an American singer, songwriter, and actress. She had limited exposure to secular music during her childhood and pursued a career in gospel music as a teenager. After releasing her debut studio album, Katy Hudson, in 2001, Perry moved to Los Angeles the following year to venture into secular music. She recorded a collaborative album with the Matrix, which was released in 2009. Perry also recorded an album with Glen Ballard that was not released due to contractual complications.
In April 2007, she signed a deal with Capitol Records. Perry rose to fame in 2008 with the release of the single "I Kissed a Girl" from her second album, One of the Boys. This album produced three additional singles, including the number-three "Hot n Cold". Her third album, Teenage Dream, was preceded by the U.S. Billboard Hot 100 chart-topping singles "California Gurls" and "Teenage Dream", and later produced the number-one singles "Firework", "E.T.", and "Last Friday Night" as well as the number-three single "The One That Got Away".
