British-Irish girl group Girls Aloud have embarked on six concert tours of the United Kingdom and Ireland, five of which were in arena-sized venues. The group initially planned to embark on a Popstars: The Rivals tour in March 2003, alongside their fellow winners One True Voice as well as other contestants.
