Katheryn Elizabeth Hudson (born October 25, 1984), known professionally as Katy Perry, is an American singer, songwriter, and television personality. Perry is one of the best-selling music artists in history, having sold over 143 million units worldwide. She is known for her influence on pop music and her camp style, being dubbed the "Queen of Camp" by Vogue and Rolling Stone.
At 16, Perry released a gospel record titled Katy Hudson (2001) under Red Hill Records, which was commercially unsuccessful. She moved to Los Angeles at 17 to venture into secular music, and later adopted the stage name "Katy Perry" from her mother's maiden name. She recorded an album while signed to Columbia Records, but was dropped before signing to Capitol Records. Perry rose to fame with One of the Boys (2008), a pop rock record containing her debut single "I Kissed a Girl" and follow-up single "Hot n Cold", which reached number one and three on the U.S. Billboard Hot 100 respectively.
