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. After Red Hill ceased operations, she moved to Los Angeles the following year to venture into secular music, adopting the stage name “Katy Perry” from her mother’s maiden name. Perry subsequently began working with producers Glen Ballard, Dr. Luke, and Max Martin on an album that remains unreleased. After being dropped by The Island Def Jam Music Group and Columbia Records, she signed a recording contract with Capitol Records in April 2007. Perry is one of the world’s best-selling music artists, having sold over 143 million records worldwide. Her music has been recognized for influencing the pop sound and style of the 2010s. She has nine Billboard Hot 100 number one singles and has received various awards, including four Guinness World Records, five Billboard Music Awards, five American Music Awards, a Brit Award, and a Juno Award. Perry has been included in the annual Forbes lists of highest-earning women in music from 2011 to 2019.
