One of the Boys is the second studio album by American singer Katy Perry. It was released on June 17, 2008 by Capitol Records. During the making of the album, Perry was dropped from two record labels and went through two canceled albums. She collaborated with producers Greg Wells, Dr. Luke, David A. Stewart, and Max Martin among others on the album. All songs were written by the singer, with assistance of some other producers and writers. It was composed in a pop-rock style. A EP, Ur So Gay, which contains the album's promotional single, "Ur So Gay", was released to generate interest on the singer and the then-upcoming album.
