"I Kissed a Girl" is the debut single by American singer Katy Perry. It was released on April 28, 2008, by Capitol Records as the lead single from her second studio album, One of the Boys (2008). 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 new wave song with elements of disco and glam rock. 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 credited with increasing LGBTQ awareness in pop music.
