Katy Perry Roar - Sydney Opera House Australia

Katheryn Elizabeth "Katy" Hudson (born October 25, 1984), better known by her stage name Katy Perry, is an American singer, songwriter, and actress. She grew up in Santa Barbara, California. She pursued a career in gospel music as a teen and released her debut studio album, Katy Hudson (2001), having had limited exposure to mainstream pop music in her childhood. The following year, she moved to Los Angeles to in an attempt to venture into pop and rock music. She recorded a collaborative album with The Matrix, which was released in 2009. A solo album she worked on with Glen Ballard was also recorded and never released.

In April 2007, Perry signed a recording contract with Capitol Records. She rose to fame with the release of her single "I Kissed a Girl" from her second album, One of the Boys (2008). Perry's third effort, Teenage Dream (2010), was preceded by the 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 (T.G.I.F.)". The album became the first by a female artist to produce five number-one Billboard hits, and the second album overall after Michael Jackson's Bad (1987). In March 2012, she re-released the album as Teenage Dream: The Complete Confection, producing the number-one single "Part of Me". Her fourth effort, Prism (2013), spawned the number-one singles "Roar" and "Dark Horse".

Perry has received many awards and nominations, including eleven Grammy nominations. Billboard dubbed her as 2012's Woman of the Year. She has made the Forbes list of "Top-Earning Women In Music" for 2011, 2012, and 2013. Perry remains the only artist to spend 69 consecutive weeks in the top ten of the Hot 100. She has sold over 11 million albums and 81 million singles worldwide as of November 2013. She has six quintuple-platinum certified singles in the United States, more than any other artist.

Perry has ventured into celebrity endorsement and released fragrances Purr, Meow!, and Killer Queen. In late July 2011, she made her film debut voicing Smurfette in The Smurfs. In early July 2012, she released a 3D autobiographical documentary film, Katy Perry: Part of Me, which concentrated on her life as a touring artist and the dissolution of her one-year marriage to English actor and comedian Russell Brand.
