Katheryn Elizabeth Hudson (born October 25, 1984), known professionally as Katy Perry, is an American singer and songwriter. After singing in church during her childhood, she pursued a career in gospel music as a teenager. Perry signed with Red Hill Records and released her debut studio album Katy Hudson under her birth name in 2001, which was commercially unsuccessful. She moved to Los Angeles the following year to venture into secular music after Red Hill ceased operations and she subsequently began working with producers Glen Ballard, Dr. Luke, and Max Martin. After adopting the stage name Katy Perry and being dropped by The Island Def Jam Music Group and Columbia Records, she signed a recording contract with Capitol Records in April 2007. Perry has received many awards, including four Guinness World Records, a Brit Award, and a Juno Award, and been included in the Forbes list of "Top-Earning Women In Music" (2011–2016). Her estimated net worth as of 2016 is $125 million. She is one of the best-selling musical artists of all time, having sold 100 million records globally throughout her career. In film, she released an autobiographical documentary titled Katy Perry: Part of Me in 2012, and voiced Smurfette in the 2011 film The Smurfs and its sequel in 2013.
