Katheryn Elizabeth Hudson, known professionally as Katy Perry, is an American singer, songwriter, and television personality. She is one of the best-selling music artists in history, having sold over 151 million records worldwide. Known for her influence on pop music and her camp style, she has been dubbed the "Queen of Camp" by Vogue and Rolling Stone.
At 16, Perry released a gospel album titled Katy Hudson (2001) under Red Hill Records, which was unsuccessful. She moved to Los Angeles at 17, adopting her stage name from her mother's maiden name. Following a series of professional setbacks, Perry signed to Capitol Records and rose to fame with the pop rock album One of the Boys (2008). Its singles, "I Kissed a Girl" and "Hot n Cold", reached number one and three on the U.S. Billboard Hot 100 respectively. Perry's disco-influenced pop record Teenage Dream (2010) became the only album by a female artist to spawn five U.S. number-one singles: "California Gurls", "Teenage Dream", "Firework", "E.T.", and "Last Friday Night (T.G.I.F.)". Its reissue, Teenage Dream: The Complete Confection (2012), produced another U.S. number-one single "Part of Me".
