"I Hate This Part" is a song recorded by American girl group the Pussycat Dolls for their second studio album Doll Domination (2008). It was written by Wayne Hector, Lucas Secon, Jonas Jeberg, Mich Hansen and produced by the latter two and Ron Fair. The track was initially intended for Leona Lewis and later for Nicole Scherzinger's unreleased solo album Her Name Is Nicole. After the album's cancellation, the song was given to the group. Musically, "I Hate This Part" is a pop ballad with elements of grinding R&B and dance music. Lyrically, it sees Scherzinger conversating with a partner just before they break up, adopting breathy and emotional vocals. The song was released as the third single from Doll Domination on October 14, 2008, by Interscope Records.
