What Will the Neighbours Say? is the second studio album by English-Irish girl group Girls Aloud, released by Polydor Records on 29 November 2004. Following concerns at the label over sales of their debut album, Sound of the Underground (2003), Polydor commissioned Brian Higgins and his production team Xenomania to produce its follow-up in its entirety. Recording took place at Xenomania's studio in Kent, with all five group members contributing to the songwriting.
