Katheryn Elizabeth "Katy" Hudson (born October 25, 1984), known by her stage name Katy Perry, is an American singer, songwriter, businesswoman, philanthropist, and actress. She was born and raised in Santa Barbara, California. Having had very little exposure to mainstream pop music in her childhood, she pursued a career in gospel music as a teen and released her debut studio album, Katy Hudson (2001). She also recorded a second solo album which never received release. In 2007, Perry signed a recording contract with Capitol Records and adopted her current stage name. The following year, she came to prominence with her second studio album and first mainstream release, One of the Boys (2008, which produced singles "I Kissed a Girl", "Hot n Cold", "Thinking of You" and, "Waking Up in Vegas". The project was further promoted through the Hello Katy Tour. Perry's third record, Teenage Dream (2010), spawned the Billboard Hot 100 chart-topping singles "California Gurls", "Teenage Dream", "Firework", "E.T." and "Last Friday Night (T.G.I.F.)". In doing so, it became the first album recorded by a female artist in history to produce five number-one hits, and the second album overall behind Michael Jackson's Bad (1987). Perry embarked on the California Dreams Tour following its release. In 2012, it was reissued as Teenage Dream: The Complete Confection and contained the number-one single "Part of Me". Her fourth album, Prism, was released in 2013, and is influenced by pop and dance. It has spawned the number-one singles "Roar" and "Dark Horse".  Katy Perry sang at the Super Bowl XLIX in 2015.
