Katheryn Elizabeth Hudson (born October 25, 1984), 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. Perry is known for her influence on pop music and her camp style, being dubbed the "Queen of Camp" by Vogue and Rolling Stone. The world's highest-paid female musician in 2015 and 2018, she was named by Billboard as one of the greatest pop stars of the 21st century.
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 to venture into secular music, and later adopted her stage name from her mother's maiden name. Perry recorded an album while signed to Columbia Records, but was dropped before signing to Capitol Records. She rose to fame with One of the Boys (2008), a pop rock album 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.
