Girls Aloud are an English-Irish pop girl group, which was created through the ITV talent show Popstars: The Rivals in 2002. The group comprised singers Cheryl, Nadine Coyle, Sarah Harding, Nicola Roberts and Kimberley Walsh. The group achieved a string of twenty consecutive top ten singles in the United Kingdom, including four number ones.

After the success of their first single "Sound of the Underground", Girls Aloud spent five months recording the follow-up single and their debut album. Sound of the Underground was completed in April 2003 and released the following month. The album entered the charts at number two and was certified platinum by the British Phonographic Industry. The second single, "No Good Advice", was also released in May 2003 to similar success. Girls Aloud's third single, "Life Got Cold", charted at number three in August 2003. In November 2003, Girls Aloud released a cover version of the Pointer Sisters' 1980s dance hit "Jump". The single, which charted at number two, accompanied a new edition of Sound of the Underground.  After a brief hiatus, Girls Aloud released "The Show" in June 2004, the first single from What Will the Neighbours Say?, the group's second album. The single entered the charts at number two. The next single, "Love Machine", also peaked at number two in September 2004. Girls Aloud then recorded a cover of The Pretenders' "I'll Stand by You" which was released as the official Children in Need charity single. The song was not well received by critics; however, the cover became Girls Aloud's second number one single, holding the position for two weeks.  The album What Will the Neighbours Say? was entirely written and produced by Xenomania. Upon its release on 29 November 2004, the album charted just outside of the top five and was quickly certified platinum. The final single from the album, "Wake Me Up", was released in February 2005. It charted at number four, making it their first to miss the top three. In early 2005, the group was nominated for a BRIT Award for Best Pop Act. Following the album's success, Girls Aloud announced their first tour What Will the Neighbours Say? Live, which took place in May 2005. The group also released its first DVD, Girls on Film.
