Girls Aloud are an English-Irish pop girl group based in London. They were created through the ITV1 talent show Popstars The Rivals in 2002. The group consists of Cheryl Cole (née Tweedy), Nadine Coyle, Sarah Harding, Nicola Roberts and Kimberley Walsh. They are signed to Fascination Records, a Polydor imprint. The group achieved a string of twenty consecutive top ten singles, including four number ones, and two number one albums in the United Kingdom.

All of their albums have been certified platinum, with their albums The Sound of Girls Aloud, and Out of Control both selling over one million copies. They have been nominated for five Brit Awards, winning the 2009 Best Single for "The Promise".

Girls Aloud's collaborations with Brian Higgins and his songwriting and production team Xenomania have earned the group critical acclaim, due to an innovative approach to mainstream pop music. The group has become one of the few UK reality television acts to achieve continued success, amassing a fortune of £25 million by May 2010.

Guinness World Records lists them as "Most Successful Reality TV Group" in the 2007 edition. They also hold the record for "Most Consecutive Top Ten Entries in the UK by a Female Group" in the 2008 edition, and are credited again for "Most Successful Reality TV Group" in the 2011 edition.
