Full of bubbly songs and risqué references, One of the Boys is the second studio album by American artist Katy Perry. Released in 2008, the album served as Perry’s re-introduction to the world of music (after having previously released an album under the name Katy Hudson), and thus is actually her first studio album released as Katy Perry. Lyrically and thematically, the album largely explores flirtatious-if-innocuous and annoyed ideas of romance and sexuality, as well as a few songs about overcoming struggles and self-discovery. The album also marked Perry’s reinvention from her previous Christian-Pop background, and introduced her then-signature retro-inspired kitsch style to the world.
The first single released from the album, “I Kissed a Girl”, became her first Billboard Hot 100 number-one single. Of the albums other three singles, only “Thinking of You” failed to break into the Billboard Top-10. The album’s second single, “Hot n Cold” also went on to perform well, and along with “I Kissed a Girl” is one of the album’s most memorable songs amongst Perry’s (now considerably expanded) lineup.
To further promote the album, Perry embarked her first world tour: “Hello Katy Tour”.
As of August 28, 2020, according to Billboard, the album has sold a total of 1.73 million copies in the United States.
