"I Kissed a Girl" is the debut single of American singer Katy Perry from her second studio album, One of the Boys (2008). It was released on April 28, 2008, by Capitol Records as the lead single from the record. Perry co-wrote the song with Max Martin, Cathy Dennis, and its producer Dr. Luke, with additional production from Benny Blanco. "I Kissed a Girl" is a pop-rock, electropop, and disco song with elements of new wave. Perry stated its lyrics are "about the magical beauty of a woman." The song sparked controversy for its handling of bi-curious themes, but in retrospect has been viewed as the beginning of LGBT awareness in pop music.
