Teenage Dream is the third studio album by American singer Katy Perry. It was released on August 24, 2010, through Capitol Records. Musically, the record contains pop songs with elements of disco, electronic, rock, funk, house, Hi-NRG, and hip hop. Lyrically, it revolves around young love, partying, self-empowerment, and personal growth. Perry co-wrote every song on the album, and also worked with a number of producers and writers, including Dr. Luke, Max Martin, Benny Blanco, Tricky Stewart, Stargate, Greg Wells, Bonnie McKee and Ester Dean.
 
The album was preceded by the number-one singles "California Gurls" and "Teenage Dream", and later produced the number-one singles "Firework", "E.T.", and "Last Friday Night (T.G.I.F.)". Its sixth — "The One That Got Away" — peaked at number three on the Billboard Hot 100. Teenage Dream is the second album in history to produce five number-one singles (after Michael Jackson's 1987 album Bad), and the first by a woman to achieve this milestone. All six of the aforementioned singles, in addition to two from its 2012 reissue Teenage Dream: The Complete Confection, have sold over two million digital downloads each in the US, setting a record in the digital era for the most multi-Platinum singles from one album, breaking the previous record of Fergie's debut album The Dutchess (2006), which had five multi-Platinum songs. To promote the album, Perry embarked on the California Dreams Tour from 2011 to 2012.
